What is the Vacuum Casting?

The vacuum casting technology which uses prototype (SLA laser rapid prototyping piece, CNC products) to make silicone mold under vacuum, and is poured under vacuum conditions, such as PU, ABS, etc. Vacuum casting is also used to clone the prototype or copy the piece. It has different types including vacuum mould casting, vacuum pressure casting, vacuum sand casting and so on. This method is especially suitable for small batch production. It is a low-cost solution to solve experimental production and small batch production in a short time, and can also meet the functional test proofing of some structurally complicated engineering samples.

Vacuum Casting Materials

We offer a wide range of material options: ABS, PP, PC, PMMA, POM, high temperature resistant materials, soft rubber, silicone rubber, etc. Varieties of materials are available to make silicone molds comparable to injection molded parts. The following pictures are rubber, PC-like material, ABS-like material, POM-like material and transparent material.

We have the world's most advanced vacuum casting equipment, and provide post-processing lines such as polishing, painting and assembly. We can provide small batch production of small and medium-sized parts quikly. If you are looking for reliable vacuum casting service, please contact our professional team at info@prototop.com or contact us by visiting our website, we will provide quotes and suggestions free of charge.
Vacuum Casting Process

1. Make a silicone mold by using the master made by CNC machining and 3D printed.

2. Put the silicone mold into the vacuum molding machine.

3. Inject liquid epoxy resin and heat to cure.

4. After the curing is completed, take out the same part as the Master from the silicone mold, and one silicone mold can be used for 20 times.
Advantages of Vacuum Casting

The cost is low and the production cycle of the product is relatively short. Less waste and processing costs are much lower than CNC machining and 3D printing.

It is suitable for the processing and production of small batch products. After making an original version, it can be copied according to the original version, and the production efficiency is high.

Good mold operation. The soft molds after curing are all transparent or translucent, have good tensile strength, and are easy to cut and shape.

The probability of processing failure is small. As long as there is no problem with the original, the copy will naturally not go wrong.

Good repeatability. The silicone for molding has good fluidity before curing, and the fine structure and decoration of the model can be accurately maintained with vacuum defoaming.

Prototype Your ldeas Before Manufacturing

As a professional prototype manufacturer, WayKen has the ability to deliver the finest visual design models, full-functional engineering prototypes, or short-run and low-volume manufacturing services, allowing you to verify your design thoroughly, and help you focus on the key elements of product development.

Concept

Create your Proof-of-Concept prototype and turn your ideas into reality. lt's important to keep the conceptualization process moving and ideas flowing along the product design process.
Presentation

Show a presentation model that's nearly identical to the real product to focus groups, trade shows, or marketing activities. They can see it, hold it, and examine it from every angle.
Engineering

Build up engineering prototypes to ensure products that are designed for manufacturing, and tested for functionality, manufacturability, and viability through a series of validation phases.
Low-Volume

Low-volume manufacturing allows you to move smoothly from prototype to production, promotes design iterations more flexible, reduces risk, and saves production costs and time to market.

What do Clients Say about Prototop's Service?

Prototop always insists on the quality and effiency of our work. We put clients' satisfactory in the first place. Here are some comments that we've received from our clients.

Hi Adella

Hope everything goes well with you too.

I got the prototype and sample yesterday.

They look good and totally fit my expectation.

You guys did a great job!

I will definitely contact you again for future projects. Best regards.
