Vacuum Cast Plastic Enclosure Prototypes

Detailed Description

Our vacuum cast plastic enclosure prototypes are produced for projects requiring realistic plastic housings before investing in injection molding tooling.

A master pattern is first manufactured, typically by CNC machining or high-resolution 3D printing. A flexible silicone mold is then created around the master and used to cast polyurethane resin under vacuum. The process helps reduce trapped air while reproducing fine surface details and complex enclosure geometry.

Housing features such as screw bosses, openings, ribs, snap structures and assembly interfaces can be reproduced for appearance evaluation, functional testing and low-volume product trials.

Available Surface Finishes

• Matte Finish: Suitable for consumer electronics and industrial housings.
• Gloss Finish: Creates smooth decorative exterior surfaces.
• Painting: Supports custom colors and appearance prototypes.
• Texture Replication: Selected master textures can be transferred through the silicone mold.

Structural & Functional Breakdown

• Integrated Boss Structure: Supports screws, inserts and internal component mounting.
• Snap-fit Structure: Allows prototype housing assembly without permanent fastening.
• Connector Opening Structure: Reproduces ports, slots and external interfaces.
• Internal Rib Structure: Adds localized support and recreates molded-product geometry.

Key Features

• Injection-mold-like Appearance: Suitable for visual and ergonomic validation.
• Low Tooling Investment: Silicone molds cost less and require less preparation than production molds.
• Small-batch Repeatability: Multiple similar components can be reproduced from one master.
• Flexible Resin Selection: Different ABS-like, PP-like and PC-like behaviors can be simulated.

Applications

• Electronic Enclosures
• Control Devices
• Instrument Housings
