Why Does PA LCP+50%GF Require a Special Injection Molding Screw?

PA LCP+50%GF is a high-performance engineering plastic containing a high percentage of glass fiber reinforcement.

Compared with ordinary plastics, this type of material has:

  • Higher wear resistance
  • Stronger abrasive characteristics
  • Higher processing requirements
  • Greater requirements for screw surface hardness and durability

During injection molding production, the screw needs to withstand continuous friction from glass fiber particles.

Therefore, selecting the correct screw material and manufacturing process is important for:

  • Improving screw service life
  • Maintaining stable plasticizing performance
  • Reducing production downtime
  • Improving molding consistency

For high glass fiber reinforced plastics, customers usually need to evaluate:

  • Injection molding machine model
  • Plastic grade
  • Glass fiber percentage
  • Screw diameter
  • Screw structure
  • Surface treatment
  • Production requirements

A standard screw solution may not always meet the requirements of advanced engineering plastics.

  • Dust contamination
  • Moisture exposure
  • Surface damage

4. Foam Cushion Protection

Additional foam protection is applied to reduce impact during transportation.


5. Secure Packing

The screws are placed into shipping boxes and securely fixed.


6. Document Verification

Product information and shipping documents are checked before final delivery.
