Case Introduction

In this case, the customer produces PVC power connector plugs, requiring equipment that supports multi-cavity molds, short cycle times, and high stability. We configured a C-type vertical injection molding machine with a T-type double sliding table, enabling continuous, high-efficiency production for a 1×6 plug mold.

Solution

C-Type Machine Structure

The open-frame design of the C-type machine provides ample operating space, ideal for insert-molded products with metal pins. Its stable mechanical layout minimizes insert deviation, making it a standard machine type in the plug-molding industry.

45T Clamping Force

45 tons of clamping force is perfectly matched for a 1×6 plug mold, preventing flash, mold mismatch, and core shifting. This tonnage protects the mold while ensuring consistent molding pressure.

97–150g Injection Volume (Optional Screws)

PVC is sensitive to temperature and shear, and an adequate injection volume ensures stable plasticizing and complete filling. Optional screw sizes allow optimization for different plug designs while avoiding overheating or short shots.

T-Type Double Sliding Table

For short-cycle plug products, the double sliding table enables mold opening and unloading to proceed simultaneously, significantly faster than rotary structures. This setup typically boosts output by 35%–50% for 1×6 molds, making it an industry-preferred solution.

Servo Motor System

The servo system provides precise low-speed control, reducing common PVC defects such as burning and decomposition. It also saves 30%–60% energy, ideal for factories with multiple machines operating continuously.

Customer Benefits

①Significant output increase: The T-type double sliding table enables continuous operation, improving overall productivity by 35%–50%.
②Higher molding stability: Servo control ensures smoother injection curves, reducing PVC issues such as scorching and under-filling.
③Improved yield rate: The stable 45T clamping force ensures accurate pin encapsulation with no flash and consistent dimensions.
④Lower production cost: Lower energy consumption and efficient multi-cavity production reduce cost per part.
