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.

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.

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.
