#polyurethane casting

Vacuum casting is a low-cost but reliable method that uses CNC or 3D printing to produce a small number of high-quality prototypes based on the master model and then produces more products through vacuum coating. It is an ideal solution for forming parts in a short time.

Why would we choose vacuum casting to make our prototype?

Vacuum casting process which is using a master prototype to make a silicone mould, and then produces the reproduction via pouring the material into the silicone mould. Vacuum casting is usually used for small batches production because the cost of the silicone mould is lower than the steel mould. Also, the production lead time of vacuum casting is shorter than other processes, such as CNC machining and injection moulding. Low cost and fast production, that’s why vacuum casting products with better market competitiveness. Therefore, most people prefer using the vacuum casting process to manufacture their low volume prototypes for checking the market when they develop a new product.

However, there is one imperfection of the vacuum casting technology is that it cannot produce metal parts, just for the plastic parts. Such as TPU or other similar plastic material. But please take notice, the vacuum casting is using similar plastic, like ABS, not pure ABS, it is similar ABS, but it does not affect the strength of the products. In the end, the vacuum casting process is a nice choice when we want to make some small batches of production plastic prototypes. Vacuum casting services is advantages of high strength, high efficiency, short production cycle, simple process, and low cost, it is suitable for small batch trial production in the process of product development.

At E-make, our engineers use advanced equipment and technologies such as 3D printing, multi-axis CNC machining, and fast tooling to make your design quickly and accurately come true, and our prices are very low (often as low as 50% of the price will be paid in Europe or North America). You design it, we do it.

Painting is one of the most extensive processes for the surface of the prototype. The effect of prototype painting have: matte, half matte, glossry. can do variety of colors, textures, brushed, leather, elastic feel, etc. Why does the model need painting? What are the benefits of painting?

Painting for the prototype, has the following benefits:

   can cover the surface defects of the prototype;

 2. can reached      various colors, gloss, appearance effects and feel by painting.

3. can increases the hardness and wear resistance of the     prototype surface.

 Generally speaking, the painted products have a good appearance, and at the same time can increase the friction performance of the product, and protect the internal structure of the parts from being easily worn away. However, coloring on some prototypes is very difficult, such as POM and PP materials. They are not very stained after coloring, and the color will fade as soon as they are rubbed.

PU is polyurethane. Polyurethane casting material has a wide range of uses, so PU material prototype are also very common in daily life. Since it is a common material in life, what are its characteristics?

Features of PU:

1.   The PU material has good physical properties, resistance to bend, good flexibility, and it has high tensile strength and air permeability.

2.   PU material has high air permeability, high peel strength and high-water pressure resistance, so PU material is an ideal material for the surface and bottom layers of waterproof and breathable clothing fabrics.

3.   The pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather.

4.   It has thermoplasticity, spinnability, and can be made into plastics and fibers.

5.   No scratches, no noise. Long service life and cost reduction.

6.   Temperature resistance is -20℃ to high temperature 120℃.

7.   Polyurethane products are pollution-free, non-toxic and tasteless.

Disadvantages of PU materials:

The cost of PU materials is high, and the price of some special requirements of PU fabrics is 2-3 times higher than that of PVC fabrics. The pattern paper required for general PU fabrics can only be used for 4 to 5 times and then be scrapped.

Prototype models can avoid the risk of producing molds, reduce the time for products to come out, and have a great help in seizing the market. You can also use the prototype products for publicity planning before the development and design of the model, and even make early market sales. And the production site management work. Prototype models are divided into three categories: appearance prototypes, structural prototypes, and vacuum casting.

Appearance prototypes are mainly used to test product appearance specifications,color matching, material interaction, cost evaluation, and market research; Structural prototypes are key to interactions between the internal installation structure of the product, material compressive strength analysis, characteristic inspection, and Cost evaluation,new product investment,etc.,thereby reducing the risk of immediate production of molds.

vacuum casting services are mainly used to test various characteristics of new products in small batches, further improve the feasibility analysis of mass production of new products, and can also be used to attract new products.

Prototype can be divide into CNC prototype ,SLA prototype ,vacuum casting prototype .Today we will introduce how to make vacuum casting prototype .

1,3D printing a prototype

 Before make vacuum casting mold ,we need to make a prototype first.The prototype can be make from more common ABS material ,CNC or 3D printing both ok.The surface effect of the prototype determines the surface effect of the subsequent copy batch prototype. So the prototype surface need do better.

 2,silicon mold

When the prototype is ready,we will start making silicon mold.First fix the prototype ,fix the electric board or ABS board in five directions of the prototype (left, right, front, back and down), then inject the silicon.After 8 hours of drying,cut open the silicon mold ,take out the prototype .In this time ,the silicon mold ready.

 3,make vacuum casting prototype

Bake the mold for 1 hour at a constant temperature of 100 degrees, and then take out the mold to cool down in its natural state, or the fan can cool down, it cannot be cooled in water, if it is cooled in water, the product will definitely shrink!

After cooling down to room temperature, pour the liquid gum material into the silicone mold and dry it. The service life of the transparent silicone mold is about 8 to 10 times. Put the material in the oven for 2 hours, take it out and let it cool down to room temperature to open the mold and take out the product.

 The E-make team has more than 30 years of combined experience in rapid 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.
