The Importance Of Painting Prototype

/in , /by

The Importance Of Painting Prototype
Painting process is one of the surface treatment that be widely use for products.Below is some advantage of the painting for product.
1.Painting can cover the slight flaw on the surface of product;
2.Product can obtain a variety of surfaces by painting,such as color and gloss.
3.Increasing the surface hardness and the conflict of resistance of parts.

In a word,painting can beautify the appearance of product and protect the product structure from damage.For example,the appearance of the CNC machined prototype after painting is very closed with the finished product.But there are some plastic is without stronger color adhesion and is hard to painting color,such as POM and PP.

Die casting-Aluminum part

/in , , /by

Aiming at the shortcomings of die-cast aluminum: “Due to the high speed of liquid metal filling the cavity when die-casting aluminum, the fluid state is unstable, so the general die-casting aluminum method is used, and the casting is prone to pores and cannot be heat treated.” So it is easy to cause poor appearance of the product,and the defective rate of the product is very high.

Now there is a new process: extrusion aluminum + die-cast aluminum. That is, the exterior surface of the middle frame of the product is extruded with profile, and the internal structural surface of the middle frame is die-cast. The process is to place the aluminum profile into a mold after preliminary CNC processing, and then die-cast the internal structure. At high temperatures, the contact surface between the profile aluminum and the die-cast aluminum is partially molten, which makes the two more closely integrated.

Advantage:

  • Significantly reduce CNC machining time, improve efficiency and reduce costs.
  • Close structure
  • The appearance surface anodizing not affected by die-cast aluminum, avoiding the defects of die-cast aluminum anodizing.

The E-make team has more than 30 years of combined experience in prototype machining, CNC manufacturing（metal,plastic parts machining）, vacuum casting service and 3D printing service.

What Is The Difference Between Anodizing And Painting

/in , /by

What Is The Difference Between Anodizing And Painting

1.Material.
Painting can be used in plastic made parts and metal made parts,but anodizing only can be used in aluminum alloy made parts.

2.The persistance of color.
Painting is making the parts coated with a layer paint,which might will come off with the time goes on.Anodizing is making the color permeate into the inner of prototype and there will have oxidation film be formed on the surface of the prototype,which are not easy to fade.

3.The effective of surface are different.
The color by anodizing has metal texture and looks with high quality.

What are the classifications of toy prototypes?

/in , , /by

According to the materials used, the processing of toy prototypes can be divided into: plastic silicone and metal materials.

And According to the product effect to be achieved by level, it can be divided into: appearance, structure and main function prototype.

  1. Appearance prototype: Mainly inspect the appearance of the design, which requires high requirements for appearance surface finish and accurate color, so the internal treatment requirements are not high.
  2. Structure Prototype: It mainly detects the rationality of the structure of the product. The requirements for the size of the product are relatively high, and the requirements for the appearance are relatively low.
  3. Functional prototype: It is required to achieve the same appearance, structure and function as the real product, which can be understood as a finished product that is not on the market, so it is a type of prototype with high requirements and difficulty.

The Advanatge And Disadvantage Of SLS 3D Printing

/in , /by

The Advanatge And Disadvantage Of SLS 3D Printing

Advantage

1.Most materials can be used for SLS 3D printing,such as ceramic powder,nylon powder,etc.

2.The precision of parts by SLS printing is about ±0.2mm.

3.SLS printing do not require the structural support when working.

4.The material for SLS printing have high utilization,and the price is cheaper than the material for SLA printing.

 

Disadvantage

1.The surface of parts by SLS printing are rough.If you need the parts with smooth surface,SLA printing will be better.

2.There will have bad smell when printing.

3.The machining time is longer than SLA much because SLS printing need the preheating time and the cooling time.

Electroplating surface finish of prototype model

/in , /by

Among the many surface finish processes of prototype models, the electroplating process is currently widely used.For example, door handles and decorative parts are all electroplated; now, the design of some daily consumer products is even more inseparable from electroplating.
The coatings of different metal materials have different characteristics.Can be divided into decorative, functional and protective coatings.The electroplating can Increase hardness, prevent abrasion, improve electrical conductivity, smoothness, heat resistance and beautiful surface.

Nylon,we usually call PA66,which widely be used in making prototype,even is not as widely used as ABS,but it still is important to rapid prototyping.Below is some features of nylon made parts.
Advantage
1.High mechanical strength,nice toughness and tensile strength.
2.Great fatigue resistance.The nylon parts can retain its mechanical strength after repeated bending,so we commonly make plastic gears with nylon material.
3.High softening point and heat-resistant.
4.Good rub resistance.
5.Good corrosion resistance

Disvantage
1.Poor water absorption and dimensional stability.
2.Poor cold-resistance.
3.Poor antistatic property.

3D printing PLA material

 

PLA (Poly Lactice Acid) is a new type of biodegradable material. It can be processed from starch raw materials , and the production process is pollution-free and can be degraded.

Material advantages:

Directly degradable environmentally friendly bioplastics, low melting point, small shrinkage ratio, not easy to warp or deform, good printing flatness, suitable for models that do not require processing.

Material weaknesses:

Temperatures above 60°C will deform PLA materials. PLA material is fragile and cannot be used to make handles for tools or parts that will drop repeatedly.

Precision:

0.2mm

Application:

Auto electronic lamps and other parts production.

Can be used for lens packaging fluid analysis RTV mold durable concept model wind test and other practical production activities

Note:

PLA can break if it is slightly bent and is not suitable for making thin things.

How to process polyethylene prototype

/in , , /by

The polyethylene prototype is mainly processed by the method of silicone vacuum casting, and the main advantages are short processing time and low cost;In addition to making polyethylene prototypes, we can also make other materials, such as ABS, PP, PC, PMMA, POM, silicone, etc.Generally, a set of silicone molds can only be used for about 10 times and cannot be used. Reuse can cause deformation and large size errors.

First of all, we need to make an original before making the silicone mold, which can be made by cnc machining or 3D printing.

Then make the silicone mold: After the original is ready, start making the silicone mold. After the silicone mold is dried for eight hours, cut the silicone mold open, and then we can take out the prototype. At this time, the silicone mold is ready.

Final injection: Inject the liquid material into the silicone mold, and it will be completed after drying. The service life of the silicone mold is about 10 times.

The E-make team has more than 30 years of combined experience in prototype machining, CNC manufacturing, vacuum casting service.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.
