Recently, our company participated in the 24th DMC International Mould Technology & Equipment Exhibition, held at the Shanghai New International Expo Centre from June 4th to 7th, 2025.

The advantages of Electrical Discharge Machining (EDM) in plastic mold manufacturing are mainly reflected in its "ability to machine complex shapes," "suitability for high-hardness materials," "high precision and excellent surface quality," and "good machining stability."

In injection mold processing, machining is one of the core stages in the entire mold manufacturing process, playing a foundational role in determining the mold's structure, precision, and functionality.

Injection molds are prone to deformation during heat treatment, which affects their precision and service life.

The choice of raw materials for plastic gears is critical, directly impacting their service life, noise levels, transmission efficiency, and cost.

Food-grade injection molding refers to the injection molding process used to produce plastic products that come into contact with food (e.g., utensils, food packaging containers, cups, etc.). Such products must adhere to stringent hygiene and safety requirements for raw materials, equipment, production environments, and operational standards.

Flow marks or streaks are common visual defects in injection molding, appearing as uneven color distribution, striped patterns, or cloudy traces on the surface of plastic parts.

PET (polyethylene terephthalate) is a crystalline thermoplastic widely used in injection-molded products such as bottle preforms, transparent items, and packaging containers. Due to its high crystallization temperature and hygroscopicity, PET injection molding requires specific process conditions to ensure product quality and performance.

Before an injection mold is put back into use, it must undergo thorough inspection and maintenance to ensure proper operation, extend mold life, and prevent quality issues during production.

In the design and manufacturing of plastic molds (injection molds), certain component interfaces require clearance (relief) to prevent interference, friction, and jamming, or to ensure proper mold opening/closing and molding functionality.
