Vacuum Casting

What is vacuum lamination?

Ideal for functional testing of prototypes and small batch production

Vacuum composite molding, also known as silicone composite molding or hand-board composite molding, is an economical alternative to small-batch injection molding of plastic parts.Usually, the mold uses CNC or SLA parts as prototypes, made of silicone material, and polyurethane PU material is cast through the process of vacuum injection to make parts.Replicas can accurately replicate the structure, detail and texture of the prototype and provide a consistent surface finish for results similar to injection molding production.

Process advantage

excellent surface finish

Compared with CNC prototyping or 3D printing, vacuum composite molding can provide better surface quality.
High precision and fine details

Vacuum overmolding provides high precision and high detail parts at production quality levels.
wide selection of materials

Polyurethane materials for vacuum casting can be rigid, elastic, transparent, and various colors.
Fast delivery

10 to 15 days can produce as many as 50 prototypes with certain functions.
cheap silicone mold

The silicone overmolding process eliminates the need to invest in expensive and time-consuming injection molds.

Materials for Vacuum Lamination

Polyurethane resins are polymers with a wide range of properties and uses.We offer a variety of polyurethane materials to suit your application, including Hei-Ca st from Japan and A x son from France.It is a material with certain characteristics, similar to engineering production plastics, such as ABS, PMMA, PC, PP, PA, etc.Cast parts can range from clear and translucent to colored, from soft rubber to hard plastic.Various materials include impact resistant, high temperature (1 2 0°C) or fire resistant (UL 9 4 -V0), glass filled resins and silicones of varying hardness.

common problem

Q What type of surface treatment does Xinyecheng provide?

A We offer a variety of finishing services to achieve almost any look and feel for your parts.We provide care for metal, texturing for injection mold tooling, metal and plastic painting, and more.

When should I choose vacuum casting services?

vacuum castingMolding is a method of producing high-quality prototypes or low volumes formed from inexpensive silicone molds.Copies made in this way show good surface detail and fidelity to the original model.
When should I choose CNC machining services?

1. Machined parts have the true properties of the material you choose.Our process allows you to machine parts from solid plastic blocks and metal blocks in the same time frame.

2. We mill and turn parts quickly.Typical quantities are one to 200 pieces and manufacturing time is 1 to 3 working days.We offer product developer parts machined from engineering-grade materials suitable for functional testing or end-use applications.

3. CNC machining is more expensive than plastic 3D printing, but the most viable option for metal vision prototyping given the high cost of metal 3D printing and metal casting.
What kind of tolerances can be achieved in production and processing?

There is no given set of tolerances that works for all processes and materials.In each case, the final tolerance on your part will depend on a number of factors, including but not limited to:

1. Part size/design geometry/number, type and size

2. Material/Surface Finish/Manufacturing Process

3. Once your order is confirmed, we will review your design and provide a design for manufacturing review, pointing out any areas where the required tolerances may not be achieved.It's helpful if you can specify which areas of the design have critical tolerances of necessity, and that can be modified slightly if necessary to reduce the time and cost involved.Here are some general tolerance guidelines:

4. General tolerances for CNC machining in metals and plastics

5. Plastic injection resistance

6. The general tolerance of metal 3D printing is +/- 0.5mm

7. Expect +/- 0.15% shrinkage for vacuum casting

8. All manufacturing and technical specifications need to be clearly specified in 2D drawings in order to proceed.
