PEI material, along with other super engineering materials, can withstand temperatures exceeding 240°C, making it ideal for applications in the medical and aerospace industries.
It has an attractive natural color, but due to its high raw material cost and the challenges associated with injection molding, working with a reliable supplier, like JY Pretech, is crucial.
We have extensive experience in manufacturing PEI products.
Here is a detailed overview of the process we followed for a recently completed mold:
- Initial Preparation:
Before creating an injection mold for PEI, a thorough mold flow analysis is performed. This ensures that the product can be fully filled during the injection process without air trapping, which could lead to bubbles in the final product.
- Material Drying:
The PEI material must be dried in advance using a drying machine for at least 6 hours. Proper drying is essential to ensure the material's quality during injection.
- Precision Mold Machining:
The injection mold must be machined with high precision to ensure the quality of the final product.
- Injection Process Setup:
The mold is mounted on the machine, and injection specifications, including temperature, cycle time, and pressure, are configured. There are no universal standards for these settings; adjustments are made to determine the most suitable parameters for producing a high-quality product. This step underscores the importance of working with an experienced and skilled supplier.





- Inspection of Samples:
After obtaining successful and acceptable samples, a detailed inspection is carried out. This includes checking overall dimensions and structure to ensure they align with the design drawings. Special attention is given to identifying air bubbles, a common issue in PEI products.
- Final Sample Approval:
Once the samples meet all requirements, they are prepared for shipment.



- Inprovement:
The samples were not successfully produced after the first mold trial and still require some improvement. Please see the image below for the improvements we made to the final part.
