Material selection
Match the plastic to the operating conditions
The right insulator material depends on electrical, thermal, mechanical, and safety requirements. Share your operating environment and material specifications for review.
Dielectric performance
PC and PPSU are among the options to consider for applications requiring electrical insulation in high-voltage environments.
Temperature resistance
PEEK and PPS may suit components operating near heat sources or high-current loads.
Wear and mechanical integrity
POM and PA are options for wear-resistant guides, supports, and structural mounts.
Flame retardancy
Where required, specify materials compliant with the relevant UL94 classification for your system.
Material suitability and performance depend on the grade and application. Include any required certifications or technical data sheets with your inquiry so the raw material batch can be checked against your project standards.
Production stages
Move from prototype to repeat production
Production methods can adapt as your design and quantity requirements change.
01 / Prototype
1–20 pieces
Check fit, form, and clearances
CNC machining or 3D printing can support early design validation, including dielectric clearance checks.
02 / Validation
20–500 pieces
Evaluate parts in real conditions
Low-volume batches can be produced by CNC machining or rapid tooling for engineering validation.
03 / Production
Thousands of units
Support ongoing manufacturing
Injection molding can support repeat production with attention to material properties and dimensional accuracy across batches.
Engineering and quality
A manufacturing workflow built around your specification
For engineering teams and procurement managers, accuracy starts with clear requirements and continues through review, production, and inspection.
Drawing-based manufacturing
Parts are manufactured to your CAD files and technical drawings, with dimensional inspections on every batch.
Flexible early-stage production
CNC machining offers a route to iterate designs before committing to injection-molding tooling.
DFM support
File reviews can flag manufacturing considerations such as wall thickness, draft angles, and material stress before production begins.
Common project questions
Which files should I provide?+
Send your STEP, STP, IGES, X_T, STL, DXF, DWG, or PDF files, along with technical drawings when available.
Can I order prototypes before production?+
Yes. Prototype quantities can start at one piece, with CNC machining or 3D printing available for early validation.
What should I specify for the material?+
Provide a preferred grade or describe the electrical, temperature, wear, and flame-retardancy requirements. Include any required certifications or technical data sheets.
