Silicone prototype

/in , , , /by

Silicone is a kind of plastic products mainly used for making prototype models,and often used to make various silicone models.
Silicone prototype is used on small products or products with good patterns,It is necessary to use soft silicone rubber to make the mold. This is because the precise and small products are easy to be damaged in the mold during the prototype out of the mould time. Therefore, soft silicone must be used to manufacture the mold.
But if you are copying a large product or making a large product, you must use silicone with high hardness to making a mold to keep the product from deforming.
The E-make company is capable of making silicone vacuum casting,including vacuum casting transparent parts, high-temperature resistant silicone laminating and soft rubber materials.

1.The injection moulded parts is with high precision and small tolerance.
2.The moulded parts has small weight deviationas,generally under 0.7%.
3.The material of mould is good,which make it has great rigidity.The mold cavity also have high precision dimensions,surface roughness and positional accuracy between template.
4.Using precision injection machine.
5.Using precision injection moulding process,which can accurately control the mold temperature,molding period and the weight of parts.
6.Using the plastic material which can suitable for injection moulding process,such as PPS,PPA,PC,PMMA,PA,POM,etc.

The difference between injection moulding and rapid prototype

/in , , /by

The prototype is usually processed with plastic or metal on a CNC machine or 3D printed or vacuum casting, making several samples or small batch production.The use of the mold refers to the processing of the mold first, and then using the mold to injection mold the batch production of products. Generally, a prototype is provided to the customer for confirmation, and after the confirmation, the mold is used for mass production.

And The prototype is the sample of the product. When your design drawing comes out, the product just designed cannot be perfect in general, and may not even be able to be used. Once there is any defect in direct production, all the products will be wasted, and it will greatly waste human and material resources and time.The production cycle of prototype is short, the loss of manpower and material resources is less, can quickly find out the shortcomings of product design and then improve it, for the product design to provide sufficient basis for mass production.

The mold is the metal mold of each plastic and metal piece after the confirmation of the prototype, which can produce the parts with certain shape and size precision requirements.It is steel model commonly, to machine tool, cutlery requirement is a lot higher than processing prototype, and processing cost is also a lot higher.The commodity such as the shell of the TV set, telephone, plastic bucket that we live commonly, it is to heat plastic to pour into mould to cool molding production.

Material For Plastic prototype

/in , /by

Material For Plastic prototype
Making plastic prototype commonly use ABS,PC,PMMA,Nylon,POM and so on.Below is the material performance for reference.

ABS is the abbreviation of Acrylonitrile Butadiene Styrene plastic,which unify organically the properties of PB, PAN and PS.Therefore,ABS has good mechanical performance,such as nice impact strength,stable dimension,low water absorption, good corrosion resistance,high mechanical strength and rigidity.ABS also has great chemical properties and electrical insulation properties.For example,it can keep the shap when heating.

PC(Polycarbonate) is a transparent material that has excellent performance in mechanical property, insulating property and heat aging resistance.It usually be use for making medical prototyping and beauty equipment.

PMMA(polymethyl methacrylate),we also call it Acrylic that is a high transparency and brightness material.Main performance of PMMA is stable chemical resistance,good heat resistance and toughness,which is easy for machining and painting.

POM(polyformaldehyde) has great wear resistance,high mechanical strength and rigidness,but poor corrosion resistance and adhesiveness.

There still have other materials that can be use for making plastic prototype.Different performance’s material making different functional prototyping.Shenzhen E-Make Model Technology Co., Ltd is specialized in CNC rapid prototyping,we custom make prototypes according to customer’s requirement.If you want to realize your design,is welcome to contact us !

Which material is good for making transparent prototypes?

/in /by

Take ordinary two kinds of transparent materials, PC and acrylic as an example.From the point of polishing, the time spent on the PC prototype is relatively long, because its material properties are relatively hard, and some small places cannot be polished with force.Even where it is convenient for people to polish, the time it takes for the acrylic prototype also is long.

On the contrary, because the material performance of the acrylic material is relatively soft, then it is convenient for people to use the acrylic material as the transparent prototype.

About the transparent prototypes,The E-make team has more than 30 years of combined experience in prototype machining, vacuum casting service ,CNC manufacturing, and has a high-level technological group of 25 peoples. E-make company looking forward to having a chance to serve you! If there have anything we can do for you,please feel free to contact us!

Material For Aluminum Prototype
1.Pure aluminum plate;
In all of the aluminum plate series,pure aluminum plate is the one that including most aluminum,the purity can over 99%,which is widely be use for conventional industrial.Therefore,the production process of pure aluminum plate is more simple and the price is more cheap.The material code we usually use of the pure aluminum plate is 1050,1060 and 1100.

2.Aluminum alloy plate;
Aluminum alloy plate series 2 with better hardness,include cuprum about 3-5%,which is a parts of aviation material.

Aluminum alloy plate series 3,including manganese about 1-1.5%,is commonly used in making car prototype,refrigerator prototype because it has good rust protection.Except that,Aluminum3003,3004 and 3A21 is usually use for making medical prototype,home appliance and so on.

Aluminum alloy plate series 4 including silicon about 4.5-6%,is a nice corrosion resistance material that usually be used for making mechanical parts,building parts,welding parts,etc.

Aluminum alloy plate series 5,we also call it aluminium magnesium alloy because it includes magnesium element about 3-5%.The feature of aluminum alloy plate series 5 is low density,high tensile strength and elongation,so that it will be use for aviation,such as fuel tanker.Also,it is a good material for wire drawing process.

Aluminum alloy plate series 6 including magnesium,silicon and other element,has both of aluminum4 and aluminum5 ‘s advantages,also easy for coating.What we usually use is aluminum 6061 and aluminum 6063 for prototyping.

Small batch Vacuum casting service

/in /by

What is small batch vacuum casting , vacuum casting is one of a craft in prototype machining.To put it simply, the product prototype is suspended in the air with various supports, the upper baffle around is filled with silicone, and remove the air inside the silicone then put into the vacuum mould machine to wait for the silicone to solidify and dry. Finally, the silicone mold is cut open with a knife.
Small batch vacuum casting is an indispensable prototype machining technology, which can greatly reduce the cost of direct development of steel die. After all, customers only need dozens or hundreds of sets of products to test the market response .And if the direct opening of steel mold cost is too high, then may not be worth the loss.
What’s more,small batch vacuum casting service can be very good to solve the problem of customers, low cost, fast delivery, product quality and steel die out of the same.And importantly, if the design of the product at the time of development defects, not found in a timely manner, the cost of late mold change is much higher than small batch vacuum casting service.Therefore, the best way to test the market response to the product is to vacuum casting in small batches.
The E-make team has more than 30 years of combined experience in prototype machining, vacuum casting service ,CNC manufacturing, and has a high-level technological group of 25 peoples.The processing quality of the rapid manufacturing is stable, the processing precision is high, and the appearance is exquisite.

Rapid Prototyping

In order to verify the appearance,structure and dimensions of new product,to see if the new product’s design is perfect or not,rapid prototyping is the first step.Because we can recognize the design problem when we test the prototype.In other words,rapid prototyping can help to reduce the risk of developing mould.
According to the material used for making prototype,there are plastic prototype,metal prototype and rubber prototype.
Plastic prototype is making out of plastic material,such as television,displayer,etc.
Rubber prototype is making out of rubber material,mainly be use for displaying the appearance of product,such as car,phone,toy,etc.
Metal prototype is making out of aluminum alloy,stainless steel,etc.It is mainly be used for making high-grade product,such as laptop.
According the effect of the prototypes,there are exterior prototype,structural prototype and functional prototype.
Exterior prototypes are solid and without functionality,which made for checking the appearance of the product.
Structure prototypes are hollow,which made for checking the the rationality of the product structure.It will be functional if install electronic components into the structure prototype.
Functional prototypes need to has same appearance,structure and functionality as the finished product.That is why machining functional prototypes is harder than the exterior prototype and structural prototype.
Both of SLA/SLA 3D printing and CNC machining process can be used for making rapid prototyping.Shenzhen E-Make Model Technology Co., Ltd are specialized in rapid prototyping,is welcome to contact us for custom your design!
