The processing of vacuum casting prototype

The processing of vacuum casting prototype

 

We usually use CNC maching to processing prototype ,but the CNC tooling is hard , can only  process hard material.So if customer need to make rubber product ,we will not be able to use CNC machining .In that time ,we will use vacuum casting to process.vacuum casting is the best way to make rubber product in small quantity.So how vacuum casting to process a prototype?

1,programming.

2,make a mold.

3,Pour the liquid soft rubber material into the mold and take it out after cooling.

4,surface finish:

If those rubber product need to do color,there have two way to make color.one is painting after the product out of mold .Another is the color and the product out of mold together.This mean mix the color powder andrubber materials required by the customer into the mold, and take them out after cooling.

At this time, the product comes with its own color when it comes out of the mold. But the price will be more expensive than painting.

The surface of the vacuum casting product is smooth, and generally does not need manual processing. Which can save manual processing time.

If you have rubber products to make, please contact E-make. We are a rapid prototyping manufacturer in China, with over 10 years of experience in CNC,3D printing, vacuum casting and injection molding die-casting prototypes. We can quickly and cheaply produce high quality parts and prototype for you.

The four major importance of prototype model manufacturing

First, design optimization:Modern industrial design encompasses a wide range:For example, small items such as paper clips and pens, as well as large items such as airplanes and ships, all contain the shadow of modern industrial design, but the design of so many commodities is not the same.
Second, design evaluation:In the process of commodity design, evaluation is very important. compared with the 2D representation of the plane, the prototype model can make the details of the product clearer and the visual feeling of the product more intuitive.
What’s more,Function test: The making of prototype model can be used for some function test,and able to imitate the shape of the finished product, including functional shape, surface shape, etc.Using materials with a certain strength (such as ABS, PC, etc.), it is possible to produce functional prototype containing the internal layout,then in order to check whether the layout of goods is reasonable, wall thickness is in line with the requirements, moving parts are smooth and so on.
Finally,Reduce capital: The steady promotion of the design process is very necessary, so in the early stage of commodity design to timely find the shortcomings in the process of commodity design, timely correction, and then to prevent the subsequent problems, during which prototype manufacturing is an important part that can be used.The manufacture of prototype model is a useful method of company capital control.

CNC machine Car bumper prototype

CNC machine Car bumper prototype

CNC machining

CNC machining material according to the path set by the program , remove excess from the material.

Manual polish

After CNC machining, the surface of the bumper prototype is very rough, with many rough edges and knife marks.which need to be polished off,to make the surface of the bumper prototype look smoother,then sand it with coarse sandpaper before polishing it with fine sandpaper.

Put togethe

All parts of the bumper prototype are glued together. As the bumper prototype is made of ABS with good adhesion, its splicing has little impact on the strength.

Painting

Paint the prototype sample with color according to the customer’s requirements. If the customer has special requirements, he/she should provide us with the corresponding pantone color number.

CNC Machining Prototype

CNC Machining Prototype

CNC rapid prototyping,a processing with fast producing speed,using raw material to manufacturing prototype by CNC machine.The cnc machined parts with nice surface finish,especially after painting,silk-printing and PVD coating, the surface’s effect is very closed to the moulding machining parts.

CNC manufacturing can use ABS,POM,PC,PA,metal and other material to machining prototype for satisfying different customer’s request.However,the prototype will have very great strength and toughness if the machined material is with high quality and high density.

The Cost Of CNC Precision Machining

1.The material cost is lower if using pure ABS,PP and the other pure material.

2.CNC machining process need to program the procedure and split the parts sometimes,but one cnc machining equipment needs to be operated by 3 or 4 workers,that’s why cnc machining takes more labor cost.Therefore,the cost of cnc machining is up to the complexity and the expending of material.More complex parts needs more workload for splitting and programming,which means will takes more working time and machining cost.

The Advantage Of CNC Machining

1.Using engineering plastics has cheaper price and more selection of materials.
2.The cnc machining equipment with more stable performance,is easier to operate.
3.CNC machining processing is more suitable for producing the parts with large size and simple structure.
The Material That CNC Machining usually use
ABS 、PC、POM 、PP 、PMMA、Nylon、bakelite、aluminum alloy、Zinc alloy、mild steel、copper、stain steel,etc.,PTFE,PBT,PPS,PEET also can be machining material.
