Injection Molding Knowledge Center

A small injection molding machine uses the same need for clear pressure definitions as a larger machine. A displayed pressure value is meaningful only when its measurement or calculation basis, units and process stage are known. Identify the Pressure Basis Hydraulic pressure: a value in the hydraulic system, where applicable. Specific or melt pressure: a […]

A proper shutdown procedure for a vertical injection molding machine, especially for overnight stops or material changes, is a critical step to prevent thermal decomposition (scorching) of the plastic resin. If operated incorrectly, residual resin heated in the barrel for an extended period can lead to carbonization and discoloration. This will cause a high number

The capital investment in plastic machinery projects is significant, characterized by large production scales and considerable consumption of injection-molded plastic materials. With high labor efficiency and substantial output value, these projects represent a highly productive manufacturing organizational structure. Plastic machinery consists of various components, including mechanical devices, hydraulic systems, electrical appliances, and specialized supporting facilities.

Updated November 3, 2026. Wire injection mold maintenance should be planned around the actual tool, material and product requirements. Cleaning and preservation between runs are a different task from monitoring mold-related quality during production. Use the moldmaker’s and component suppliers’ instructions to define the work. Document the Condition at the End of the Run Record

Many customers notice a phenomenon when purchasing vertical injection molding machines: an LSR (liquid silicone rubber) machine and a standard plastic machine with a similar appearance and tonnage can have a significant price difference. Where does this price gap come from? The answer lies in two completely different molding processes and the core construction of

Updated November 3, 2026. During wire overmolding production, a mold inspection plan should connect the condition of accepted parts with the tooling and process records. This page covers production monitoring. For cleaning, preservation and storage between production runs, use the separate wire mold maintenance guide. Monitor Part Quality Against the Approved Sample Check the specified

During the injection molding process, the appearance of black or yellow scorch marks on a product’s surface is a common defect. This issue leads to scrapped parts and reduced production efficiency. It also serves as a clear signal of underlying problems with the equipment or process parameters. Understanding the root cause of scorching is the

The Role of Vertical Silicone Machines in the Mobile Phone Sector Due to its eco-friendly nature and versatility, silicone products are increasingly integrated into everyday life. Liquid silicone rubber (LSR) protective covers offer several benefits: they are non-toxic, provide excellent cushioning, display high resistance to wear, are impervious to oil and water, possess good flexibility,
