chamfer
Used to remove sharp edges and improve assembly import; it is recommended to clarify the chamfer size or give instructions for assembly edges, handheld edges and stress-sensitive areas.
Polyether Ether Ketone (PEEK)
Polyether Ether Ketone (PEEK)(polyether ether ketone) is a high-performance specialty engineering plastic with extremely high mechanical strength, excellent high-temperature resistance, and outstanding chemical corrosion resistance.

Finishing
polish
Used to improve the local appearance and feel of the mating surface; if there are appearance requirements, please define acceptable parting line/gate/ejector mark standards.
bonding
Suitable for component structure, assembly positioning and functional assembly; it is recommended to reserve positioning structure and bonding gaps in the drawings, and note the force direction and usage environment.
Why Choose PEEK (Injection Molding)
For high temperature resistance and stability needs
Suitable for functional parts scenarios that are close to heat sources, thermal environment verification or are more sensitive to dimensional stability (subject to confirmation of specific brand and working conditions).
Corrosion resistance and environmental adaptability
It is more stable in some medium environments and is suitable for structural parts related to chemical/moisture/oil pollution and other working conditions (it is recommended to clearly indicate the medium and temperature in the remarks).
Electrical insulation direction optional
When there are requirements for the integration of insulation and structure, it is easier to make "functional parts", and the consistency can be improved through structure and mold solutions.
Injection molding consistency facilitates mass production
When you want to move from small batch verification to mass production delivery, injection molding is beneficial to stabilizing batch consistency and unit cost dilution.
Recommended Applications
- High temperature resistance is preferred: Thermal environment verification, functional parts close to heat sources
- Corrosion resistance/environmental adaptability: Structural parts related to working conditions such as medium environment, moisture and oil pollution, etc.
- Electrical insulation related: Components required for structural + insulation integration
- Small batch to mass production: Requires batch consistency and replicable delivery
It is not recommended to use it directly (it is recommended to change materials/change routes)
- Highly cost sensitive and have average performance requirements: General engineering plastics or other more economical solutions can be evaluated
- Appearance display only: Evaluate lower-cost, friendlier-looking material routes
- Structure not suitable for injection molding: For deep cavities, complex undercuts, extremely uneven wall thickness, etc., it is recommended to do DFM or evaluate CNC/3D printing first.
- Unclear needs: It is recommended to write down the working conditions in the remarks, and we will help match more suitable materials/processes.
Design and DFM advice (injection molding | PEEK)
- Uniform wall thickness is preferred: Try to avoid sudden changes in thickness in large areas to reduce the risk of sink marks, warping and internal stress; it is recommended to use ribs instead of "solid thickening" for thick areas.
- Draft and parting line: For the purpose of demoulding and appearance consistency, it is recommended to reserve an acceptable range of draft and parting line for key appearance surfaces; the appearance surface should be as far away from the gate/ejector as possible.
- Rib position/reinforcement structure: The rib thickness should be reasonably matched with the main wall thickness, and priority should be given to improving rigidity while controlling shrinkage marks; fillet transitions are recommended at stress concentration locations.
- Gate/ejector position: Gates, ejector pin marks and weld lines will affect the appearance and strength; if there is an appearance surface or load-bearing direction, please specify it in the remarks.
- Assembly dimensions and tolerances: It is recommended to provide 2D markings for key hole positions/mating surfaces; if assembly accuracy is required, a "list of critical dimensions" can be indicated in the remarks.
- Parts and bonding: If the structure is complex or the mold risk is high, separate injection molding + bonding can be considered; it is recommended to reserve the positioning structure and bonding surface width, and explain the stress and environment.
