Material For Plastic prototype

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 !

Material For Aluminum Prototype

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.

Aluminum alloy plate series 7 with high hardness,high strength and nice wear-resistant,specially the aluminum 7075, is commonly used for making aluminum alloy plane model.

What kind of aluminum is best for machining your prototype,is up to your requirement of the product.Shenzhen E-Make Model Technology Co., Ltd is professional in CNC manufacturing,is welcome to contact us if you want to customized your prototype!

Custom Rapid Prototyping

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!

What Surface Finish Can Be Used For Aluminum Parts?

What Surface Finish Can Be Used For Aluminum Parts?

1.Sand blasting
Sand blasting is a process that using the impact of the high-speed sand flow to clear and coarsen the metal’s surface,which can improve the  mechanical property of the parts’ surface and Fatigue resistance.
2.Polishing
Polishing is a process that reducing the roughness of the parts’ surface to make the parts with bright and smooth appearance by the mechanical, chemical or electrochemistry.
The main polishing process is mechanical polishing,chemical polishing and electrolytic polishing.
The aluminum parts can be close to the mirror finish of the stainless steel after mechanical polishing and electrolytic polishing.
3.Wire drawing
Wire drawing is a metal working process used to reduce the cross section of wire by pulling it through a series of dies.
4.Anodizing
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.Anodizing not only can solve the problems about the aluminum’s surface hardness and anti-abrasion,but also extend the service life of aluminum.
