Sheet Metal Fabrication
Machining metal sheet material also called as metal plate fabrication,which mainly include cutting,bending,brake forming,stamping,welding,riveting and so on.Regarding sheet metal,we probably can understand that is a parts of constant thickness during processing.
Sheet metal is widely used in mechanical manufacturing,for example,we usuallly will use metal plate for making chimney,metal bucket,ventilation shaft,oiler,etc.
About the material,sheemt metal fabrication generally will use such as SPCC,SHCC,SECC,SGCC,copper,brass,red copper,beryllium copper,stainless steel (mirro surface,brush surface,matte,etc),aluminum (6061,6063,hard aluminum,etc).The manufacturer will offer their suggestion according to the use of the product,the cost that customer require.
1.SPCC mainly be used in electroplated parts and coated parts.The thickness of SPCC sheet parts is thinner than 3.2mm,with low cost and easily formed.
2.Like SPCC material,SHCC material mainly be used in electroplated parts and coated parts,with low cost.But the thickness of them are thicker than 3.0mm,also,they are hard to be formed.Mostly will be used for flat components.
3.SECC and SGCC material mostly for the parts that do not require surface treatment.Also,the cost for make them are highly.
4.Copper mostly for the product that require conduction of electricity,which will takes high cost.The surface finish for copper generally is nickel plating,chrome plating or without surface finished.
5.The surface treatment we usually will use for aluminum alloy material is anodizing,silver plating,nickel plating.
6.The section aluminum material with complex structure mostly will be used in subrack.
7.The stainless steel material made parts generally without surface finish.
The ways to cut material in metal plate machining as following.
1.The shears mostly is for cutting the simple shape material,tolerance is lower than 0.2mm,which are with low cost,but only can be used in machining the sheared strip or lump material.
2.The puncher can cutting the material into kinds of shape,the advantage of making sheet metal by puncher is with short time production,high efficiency,high tolerance and low cost,which are suitable for bulk prodcution,but it will need to make mould before producing.
3.About cutting the material by NC,we will need to programm before machining.The feature of this machining way is with low cost and tolerance is 0.15mm,but the structure of parts will be effcted by the structure of the tool.
4.We also can use laser cutting process to cut the material out of shape.Like the way of NC,laser cutting also need to programm before working,This way can cut the flat piece with complex shape,and tolerance is 0.1mm,but the cost of this way is high.
5.The saw machine can be usd in such as section aluminum,square tube, diagram tube and round bar material,also with low cost and low tolerance.

The Process Of CNC Machining
1.Confirm the machining area and the specification of machined parts.
a)Firstly,determine what process has been used to process this workpiece before and what process will be used to process it, and then confirm the relationship between these processes.
b)The condition of the workpiece before.For example,it was a casting parts or a forgeable piece or a bar parts,and the shape,the dimension,the machining allowance of workpiece and so on.
c)What area and shape need to be machined in next process.
2.Confirm the clamping way of the workpiece and design the fixture.
Select and design the fixture according to machining area,locating basis and clamping requirement of the workpiece.Mostly CNC machine will use three-jaw self-centering chuck to clapm the workpiece.
3.Confirm the machining method.
a)Determining the process principle,generally there are first rough then essence, near then far,inside then outside,the least procedure section, the shortest tooling route and special cases for special treatment.
b)In order to improve the production efficiency and ensure the finish machining quality of parts, the rough machining process shall be arranged first during cutting, and a large amount of machining allowance before finish machining shall be removed in a short time, and the allowance uniformity requirements of finish machining shall be met as far as possible.When the roughing process is finished, the semi-finishing and finishing should be arranged after the tool change.The purpose of arranging semi-finishing is when the uniformity of the remaining allowance after rough processing can not meet the finishing requirements,it can arrange semi-finishing as a transitional process,so that the finishing allowance is small and uniform.
c)Near than far is according to the distance from the machining position to the tool.Generally,to shorten the tooling distance and reduce the idle time,we will machining the position that more closed with the tool when are rough machining.Near than far is good for turning processing,whhich are the cutting conditions can be improved and keeping the rigidity of the blank or semi-finished parts.
d)For the parts need to be machined both of the inside surface and the outside surface ,we should machining the inside before outside when we are planning because it is difficult to control the size and shape of the inner surface, the tool rigidity is correspondingly poor, the durability of the tip edge is reduced by the heat of cutting,and chip removal is difficult during machining.
The above principles are not set in stone,some special cases may require a flexible approach.For example,some workpiece must be finished after rough processing to ensure its processing accuracy and quality.

Analysis of the five elements that need to be met in injection molding

/in , /by

Plastic molding is the process of making various forms (powders, pellets, solutions and dispersion) of plastics into products or blanks in the desired shape.The manufacturing process of most cosmetic packaging materials is mainly through the four key processes of mold molding, surface treatment,printing,and assembly.The molding process is an indispensable key part.Injection molding is a method of producing shapes for industrial products.Products usually use rubber injection molding and plastic injection molding.Injection molding can also be divided into injection molding compression method and die-casting method.Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes. Injection molding is realized by injection molding machines and molds.

The five elements that need to be met in injection molding are:

  1. Temperature:Temperature is the first step of injection molding.Temperature can be divided into:drying temperature,material temperature,mold temperature, these are some of the most important factors.The drying temperature is to dry the polymer in advance in order to ensure the quality of the molding,to ensure that the dry and wet of the polymer are within a certain amount;The material temperature is to ensure that the polymer is plasticized normally,and the mold is filled and formed smoothly;
  2. Speed:Speed is divided into:injection speed,Melting speed,loosening and retreating speed,opening and closing mold speed,thimble forward and backward speed.The increase of the injection speed will affect the increase of the filling pressure,and the increase of the injection speed can increase the flow length,and the product quality can be uniform to ensure the quality of the product.High-speed injection is suitable for long-process products,and the size of the product is controlled at low speed;Melting speed affects plasticizing ability,plastic mold processing is an important parameter of plasticizing quality,the higher the speed,the higher the melt temperature,the stronger the plasticizing ability;
  3. Pressure:Pressure is divided into: injection pressure,holding pressure, back pressure,clamping pressure,mold protection pressure,ejection pressure.
  4. Position:The position can be divided into:mold opening position, ejection retreat stroke,metering stroke,leg loosening amount,injection stroke,and buffering amount.The mold opening position is to ensure the normal operation of the demolding parts.The effect of the ejection back stroke on the partial spring return to the ejection limit protection.The metering stroke is to ensure that there is enough plastic to fill the mold to ensure product quality.
  5. Time:The time is divided into:cooling time,sol time,drying time, cooling time,melting time,drying time,cycle,injection time,and pressure holding time.The molding of plastic shell paintingproducts requires a certain period of time.The holding time is to prevent the melt back flow and cooling shrinkage.The cooling time ensures that the product is solidified and prevents deformation;the melting time is to ensure that the glue is fully melted;the drying time is to ensure that the product does not become elongated or defective.

The E-make company has 30 years of experience in custom-made production of injection molding.The plastic injection molding products will be exquisite in appearance,reliable in quality and delivered on time.If you want to customize the high-precision injection molding products.All information from customers was kept secret,we can sign NDA with you before starting any work.If you need any help,please feel free to contact us.

Sheet Metal Working
With the characteristics of light weight, high strength, conductivity, low cost and good mass production performance,metal plate is a technology that has been widely used in electronic and electrical appliances, communication, automobile industry, medical devices and other fields. For example,it is an essential part in computer chassis, mobile phone,and so on.
The material of metal plate widely be used in electronic enterprises is SPCC,SECC,SGCC,SUS301,SUS304,etc.There are three main types of sheet metal processing: blanking, bending and stretching. Different processing technologies have different requirements for sheet metal. The selection of sheet metal also need be considered according to the shape of the product and processing technology.The following is the impact of materials on sheet metal processing technology.
a,The influence of materials on punching process.
Punching requires that the plate material should have enough plasticity to ensure the plate will not crack during machining.The soft materials such as pure aluminum,antirust aluminum, brass, red copper and mild steel have good punching performance,which can be blanked to the parts that have a smooth section and a small inclination.The quality of the hard materials is not good after punching,such as high-carbon steel,stainless steel,duralumin and ultralumin, the section unevenness is large, especially for the thick plate material.
b,, The influence of materials on bending process.
The plate materials to be bent should have sufficient plasticity and low yield limit.The plate with high plasticity is not easy to crack when bending. The plate with low yield limit and low elastic modulus has small rebound deformation after bending, and it is easy to obtain the bending shape with accurate size. Materials with good plasticity such as low carbon steel, brass and aluminum with carbon content less than 0.2% are easy to bend and form; Materials with high brittleness, such as phosphor bronze (qsn6.5 ~ 2.5), spring steel (65Mn), hard aluminum, superhard aluminum, etc., must have a large relative bending radius (R / T) during bending, otherwise they are easy to crack during bending.
c,The influence of materials on tensile process.
Sheet metal stretching, especially deep stretching, is a difficult kind of sheet metal processing technology. It not only requires the stretching depth to be as small as possible, the shape to be as simple and smooth as possible, but also requires the material to have good plasticity. Otherwise, it is very easy to cause overall distortion, local wrinkling and even tensile cracking of the parts.

Rapid prototyping manufacturing service

/in , , /by

The inspection design prototype is not only visible,but also touchable. Therefore,the prototype can vividly reflect the artistic creativity of the interior designer in a physical way,preventing “drawing beautifully but making it unsightly”Shortcomings.So,prototype manufacturing is indispensable in the development of new products and the deliberation of product appearance.

Check the structural design.Since the prototype is installable,the prototype can visually reflect the effectiveness of the product structure and the level of difficulty of installation,which is conducive to finding problems and solving difficulties in time.

Prevent the risk of opening the mold immediately,because the cost of mold processing is generally very high.If the structure is found to be unscientific or other problems in the process of mold opening,the damage is obvious.Prototype manufacturing can prevent such damage and reduce the risk of mold release.

Make the product launch time much earlier,because of the advancement of prototype production,you can use the prototype for product promotion before the mold is developed,and even the early sales and production preparations to occupy the market as soon as possible.

According to the manufacturing process,the prototype is divided into CNC prototype and manual prototype;

CNC prototypes are mainly produced and processed by CNC machines. According to different production equipment,they are divided into laser rapid prototyping technology and CNC prototypes.

During this period,the prototypes of laser rapid prototyping technology are mainly matched with SLA prototypes,that is,prototypes produced and processed by using the skills of laser rapid prototyping technology. In fact,it matches with other CNC prototypes:CNC prototypes.That is,the CNC machine is used to produce the processed prototype model.

Advantages of CNC prototype:The advantage of the CNC prototype is that it can accurately reflect the information content represented by the engineering drawings.The surface quality of the CNC prototype is very high, especially in the middle and later stages of production and processing.The parts need to be painted.Therefore,CNC prototype manufacturing has increasingly become the mainstream of the prototype manufacturing industry.

If you want the prototype model to be close to the finished product and to detect the actual effect of the appearance,you must make a prototype model.After the prototype model is completed,it must be polished. What is the polishing of the prototype model?

Prototype model polishing is to eliminate burrs,oily dust on the surface of the part or the surface of the material,reduce the surface roughness of the surface of the product,and improve the adhesion of the coating after polishing the old paint film.Prototype model polishing can be divided into traditional manual polishing and modern polishing.

After a prototype part is CNC processed,its surface will inevitably cause many burrs and knife marks.At this time,it is necessary to manually solve this problem manually.Generally,people will choose sandpaper for sanding,or sanding and polishing.The basic appearance solutions include sanding,sandblasting,sanding and polishing,coloring,silk screen ink,and electroplating.

As a professional manufacturer,we have the capabilities to produce the finest Visual Design Models,Full-functional Engineering Prototypes or Low volume production runs that allow you to proof your designs thoroughly,and help you to focus on key elements of product development.

CNC turning machining Service

/in , , , /by

CNC turning is one of the most basic and most commonly used cutting processing methods.For most work pieces with revolving surfaces,it can be processed by CNC turning machine,such as inner and outer cylindrical surfaces,inner and outer tapered surfaces,end surfaces, grooves,threads,and rotary forming surfaces, etc. .
With the development of modern technology,there are more and more high-strength and high-hardness engineering materials.Traditional CNC turning machine has been unable to meet or realize the processing requirements of certain high-strength and high-hardness materials, while modern hard cnc turning technology can Make it possible and obtain significant benefits in production.The following is a brief introduction to the characteristics of CNC turning machining:
(1)CNC turning machining efficiency is high:
CNC turning uses large cutting depth and high work piece speed,and its removal rate is usually several times that of CNC grinding.CNC lathes can complete various surface machining in one clamping process,while grinding requires multiple installations,so the auxiliary time of CNC turning machining is shorter,and the position accuracy of each processing surface will be higher.
(2)The cost of equipment investment is low.Under the same productivity, the investment of a lathe machine is obviously better than that of a grinder,and the cost of its auxiliary system is also low.In the production of small batches of parts, CNC turning does not require special equipment, and the processing of large quantities of high-precision parts requires high rigidity, positioning accuracy, and repeat positioning accuracy for CNC machine tools.
(3)The lathe suitable for small batch flexible production is a flexible processing method with a wide range of processing.The lathe is easy to operate and the turning fixture is fast.Compared with grinding,hard turning is more suitable for the requirements of flexible production.
(4)Hard CNC turning can obtain better overall machining accuracy.
(5)CNC turning machining surface quality is excellent,processing roundness is accurate,and can ensure high position accuracy on the processing surface,Also will not produce burns and cracks during the cutting process,and most of the heat generated during the processing of the parts will be taken away by the cutting oil.

Application of ABS material in 3D printing

/in , , /by

ABS is one of the main materials for 3D printing.The reason why it can become a consumable for 3D printing is determined by its characteristics. ABS materials have heat resistance,impact resistance,low temperature resistance,chemical resistance and excellent electrical properties，Product dimension stability and other characteristics.

At present,ABS is the most stable material among 3D printing materials. It has good hot melt and impact strength,and it is also the preferred engineering plastic for fused deposition molding 3D printing process.For now,ABS is mainly pre-made into silk and powdered.The application range of ABS materials covers almost all daily necessities,engineering supplies and some mechanical supplies,and has a wide range of applications in automobiles,home appliances,consumer electronics and other fields.

Printing performance:

  1. ABS materialis quite easy to print.No matter what kind of extruder is used,the material will be extruded smoothly without worrying about clogging or solidification.However,the steps of ABS material after the extruder are a bit difficult.ABS material has the characteristic of shrinking when exposed to cold,and will partially fall off the heating plate and hang in the air,then it will be causing problems.In addition,if the height of the products that needs 3D printing is very high,the ABS material sometimes peels off the entire layer during the 3d printing process.Therefore,the heating plate cannot be omitted when ABS material is used for 3d printing.
  2. ABS material is relatively flexible,so it is suitable for making wearable products.

Strength:As long as 3D printing is carried out at an appropriate temperature and the layers of materials are firmly adhered,the strength of ABS will become quite high.But the ABS material is also flexible after 3D printing,even if it is under pressure,it will only bend and not break.

Odor: The biggest disadvantage of ABS material is that it produces a strong odor during 3d printing.Regardless of the material,it is recommended that you perform 3D printing in a well-ventilated room. This is especially true when using ABS materials.

ABS-M30 is a production-grade plastic that is specially designed for 3D printing with FDM technology.This strong and common material helps to test and repeat the work more frequently,Ultimately reduce risks and create better products,speeding up the time to market.

Due to performance reasons and the price is more suitable,3d printing ABS material it is very suitable for conceptual models and parts with medium requirements, including functional prototypes.The colors of ABS material are natural color,white,black,dark gray,red and blue.In addition,the color can be customized when 3d printing.
