Low Warpage Injection Molded Parts
Through material optimisation, mold design and molding process control we reduce warpage and deformation of injection molded parts, improving dimensional stability and precision for high precision structural components.
Plastic parts warp easily after injection molding, affecting assembly and use
Warpage is one of the most common problems in glass fibre reinforced nylon and engineering plastic components. It affects not only appearance but also assembly accuracy and dimensional consistency, and can degrade product function and reliability.
- 1Do parts warp after injection molding?
- 2Are glass fibre reinforced parts dimensionally unstable?
- 3Does deformation appear during high temperature assembly or storage?
- 4Does warpage appear after long-term use?
- 5How can flatness and dimensional stability be improved?
Glass fibre distribution and part structure are balanced in the formulation, which is the basis of low warpage performance.
High performance material combinations that improve dimensional stability
We select and compound materials for the structural requirements and use environment of each part. Reasonable glass fibre content and formulation design lower the risk of warpage.
- Glass fibre content balanced to part wall thickness
- Uniform fibre distribution in the moulding
- Alternative mineral filled systems for critical flatness
- Dimensional verification during trial moulding
Multi-dimensional control to reduce warpage and deformation
Through structure optimisation, injection parameter adjustment and cooling system design we reduce warpage risk from the process side, ensuring dimensional accuracy and consistency.
Widely used where high dimensional stability is required
Low warpage parts are widely used in office furniture, automotive, electronics, new energy and industrial equipment applications.
