Small Batch for Silicone Molding Parts
Xinprototype has rich experience and capable of handling your vacuum casting and silicone molding needs. This is a great way to make small batch production of plastic (Silicone, Rubber, ABS, PP, PA, PMMA, PC, POM) parts, and is ideal for prototypes, engineering tests, concept proofing, display demos, and low-volume production.
Advantages of Vacuum Casting
1. One mold can produce around 10–20 high-quality pieces from a single silicone mold, depending on the part specification and volume.
2. Xinprototype can produce customized plastic parts in complex shapes in a single piece, no glue.
3. Different hardness shore available from 30 to 90 degrees meet your different needs.
4. A range of surface finishes after casting is available, such as painting, chrome, etc.
The process of vacuum casting offers significant advantages, and is particularly useful for parts that have undercuts or fine details.
How to Get Vacuum Casting Parts?
Vacuum processing
The vacuum machine draws liquid material into the mold and removes bubbles and air pockets to ensure a smooth finish.
Make silicone molding
CNC machining or 3D printing produce a master model, then pour in liquid silicone to make a silicone mold.
Curing
Take the part from the silicone mold after curing, deburr etc make the appearance more perfect.
Industries served
Automotive: Appearance tuning design, ideal for car door, grill, bumper, etc. Or R&D developing a new car before opening the mold for a small batch test. Also can be used for modifying components for silicone components used in vehicle interiors.
Medical and healthcare: Suitable for diagnostic devices, surgical tools, silicone masks, and other medical-grade silicone parts.
Electronics: Used to create custom components production of silicone molds for electronic devices, wearable products, and consumer electronics.
Industrial manufacturing: All kinds of manufacturers and design companies develop new products, to test new concepts through rapid prototyping and low-volume production..
Common Questions Vacuum Casting Parts
Q1: Which materials are available for vacuum casting prototype parts?
A1: ABS, PC, PA, Rubber, Silicone, PMMA, etc. The shore hardness from 40 to 90 degrees.
Q2: What is the dimensional tolerance for vacuum cast parts?
A2: Standard tolerance is ±0.2–1.0 mm, Final depending on part size and geometry.
