Frequently Asked Questions

Q1: What is the service life of the High Precision Large Gate Mold Base? 

A1: Under normal use and maintenance conditions, the mold base life can reach 500,000-1,000,000 molding cycles. The key lies in correct use and regular maintenance, especially the lubrication and maintenance of guide pillars and bushings.

Q2: How is the mold base precision maintained?

A2: Precision is ensured by using high-quality steel, precision machining, and strict heat treatment processes. During use, the wear of guide pillars and bushings should be checked regularly, and worn parts should be replaced promptly.

Q3: Which types of injection molding machines is it suitable for?

A3: This mold base is suitable for various thermoplastic injection molding machines, including horizontal, vertical, and two-color injection molding machines. The appropriate model can be selected based on tonnage and installation requirements.

Q4: How to choose the appropriate mold base size?

A4: It needs to be selected based on the product size, molding tonnage, and mold structure. The product size should be controlled within 80% of the effective molding area of the mold base to ensure sufficient clamping force and injection pressure.

Q5: What maintenance precautions should be taken for the High Precision Large Gate Mold Base?

A5: Regularly check the lubrication of the guide pillars and guide bushings and keep them clean; avoid overloading; regularly check the parallelism of the mold plate; stop the machine immediately if any abnormalities are found.
