In the field of medical injection molding, product precision directly determines the safety and effectiveness of medical devices. However, flash (also known as burrs), as a common defect, not only affects the appearance of products but may also lead to sterilization failure due to residual contamination.

These cases underscore the unique importance of gas mark control in medical products—it not only impacts appearance quality but also relates to core performance indicators such as sealing and biocompatibility.

In the field of medical injection molding, product shrinkage (surface depressions or dimensional shrinkage) is a core defect that affects the precision and safety of medical devices. Take the piston of a medical syringe as an example; a 0.1 - millimeter shrinkage can lead to seal failure and trigger medical accidents.

However, the issue of incomplete filling in fine areas (such as micro-holes and thin-wall ribs) and corner regions (such as right-angle bends and concave structures) has become a critical bottleneck restricting product yield and performance. This article systematically analyzes the causes from three dimensions: material rheology, mold design, and process parameters, and proposes targeted solutions.

Medical injection-molded products have extremely high requirements for quality and safety. Short shots are one of the common injection molding defects, which seriously affect the performance and reliability of products.

However, the issue of strength reduction in medical plastic products is like a hidden "killer" that can seriously affect the performance and safety of the products, posing potential risks to medical work. So, what exactly are the factors that lead to the strength reduction of medical plastic products? Below, we will conduct a detailed analysis from three aspects: injection molding equipment, injection molding process, and injection mold design.

The article analyzes the causes of flash in medical injection molding from four aspects: equipment, mold, process, and material, and proposes systematic quality control solutions such as equipment selection and mold optimization to improve product qualification rates.

Every subtle change in temperature can trigger a chain reaction in the product's performance and appearance. So, just how significant is the impact of temperature on injection-molded products? Below is a detailed analysis.

Sliding control in medical plastic molds has evolved from traditional empirical repairs to precision engineering. Through structural optimization, material innovation, precise process control, and intelligent monitoring, sliding deviations can be contained within ±0.005 mm, meeting FDA’s "zero-defect" requirements for medical implants.

The article comprehensively outlines methods to prevent mold bite in medical plastic molds from five aspects: materials, structure, process, maintenance, and cutting-edge technologies, helping practitioners improve mold quality and production efficiency, and ensure the safety of medical products.

In the fiercely competitive market of medical injection molding part processing, enhancing the production volume of medical injection molding parts is a crucial factor for mass-production manufacturers to stand out. When receiving customer orders, how to handle them scientifically and efficiently becomes the core issue concerning production efficiency and customer satisfaction.

From disposable syringes to implantable stents, and from surgical instruments to diagnostic equipment housings, the safety and functionality of medical injection-molded products directly depend on material selection. This article systematically reviews commonly used materials in medical injection molding, analyzing their properties, applications, and future trends to provide insights for industry practitioners.
