Custom Vacuum Forming Services for Industrial & Large Plastic Parts
Plasticpartsmfg provides custom thermoforming services for medium and large-scale plastic components. Based in Shenzhen, China, we support product engineers and procurement teams from initial prototyping through to low-volume bridge production. Whether you require equipment enclosures, automotive panels, or custom packaging, we deliver parts that meet your technical specifications and project timelines.
Manufacturing Specifications
We utilize advanced thermoforming equipment to process a wide range of thermoplastic sheets. Our facility supports vacuum forming, pressure forming, and twin-sheet forming to match the geometry and complexity of your design.
Bridge production from 50 to 5,000 units with fast mold iteration before final steel injection commitments.

Our Forming Processes
Different geometries and material requirements dictate the forming method. We offer three primary thermoforming techniques.
Vacuum Forming
The most economical solution for single-sided parts. A heated sheet is pulled against a mold using vacuum pressure. Ideal for housings, trays, and liners.
Pressure Forming
Uses both vacuum and positive air pressure to force the plastic into the mold. This allows for sharper details, tighter radii, and textured surfaces, providing an aesthetic finish closer to injection molding.
Twin-Sheet Forming
Two sheets are heated and formed simultaneously, then fused together at the edges. This process creates hollow, rigid, double-walled parts, suitable for structural components and equipment housings.
Supported Materials
We process a variety of engineering-grade thermoplastics. If you are uncertain which material suits your application—considering factors like impact resistance, chemical exposure, or UV stability—our engineering team can provide material recommendations based on your technical drawings.
ABS
High impact resistance, commonly used for housings and enclosures.
PC (Polycarbonate)
Excellent clarity and heat resistance for durable structural components.
PETG
High transparency, often used for medical and food-grade applications.
PMMA (Acrylic)
Superior optical clarity and UV stability for transparent exterior panels.
PVC
Durable and fire-retardant properties suitable for strict compliance requirements.
HDPE / PP
Chemical resistance and structural durability for demanding industrial parts.
Secondary Operations for Finished Parts
Thermoforming is rarely the final step. To deliver a ready-to-assemble component, Plasticpartsmfg integrates secondary operations in-house, reducing supply chain fragmentation and assembly overhead.
5-Axis CNC Trimming
Precise edge profiles and complex cutouts that standard die-cutting cannot handle.
Drilling & Bonding
Precision placement of holes for mounting and structural bonding for multi-part assemblies.
Custom Printing
Silk screening or labeling for branding, warnings, and user interfaces.
Assembly & Kitting
Sub-assembly services that minimize logistics management and line time at your plant.
When to Choose Vacuum Forming
Vacuum forming is the optimal manufacturing bridge between 3D printing and high-volume injection molding.
Tooling Budget is Limited
Thermoforming molds are significantly cheaper than injection molding tools, making it the preferred choice for volumes ranging from 50 to 5,000 units.
Part Size is Large
For parts exceeding 500mm, injection molding costs become prohibitive due to mold size and machine tonnage. Vacuum forming handles large surface areas efficiently.
Rapid Iteration is Required
We can produce molds and samples in weeks, not months, allowing for faster design validation before committing to steel tooling.
Quality Control and Inspection
We mitigate procurement risk through rigorous quality control procedures across every project milestone. Click each stage to inspect verification protocols.
Project Applications
We serve diverse industrial sectors requiring durable, custom plastic components.
Industrial Equipment
Protective covers, machine guards, and ergonomic control panels.
Automotive
Interior panels, ducting, chassis protection, and exterior trim components.
Medical & Lab Equipment
Equipment housings, precision trays, and sanitary ergonomic covers.
Electronics
Custom enclosures for instrumentation, testing consoles, and IoT devices.
