In the field of medical devices and consumables, trial molding in injection molding is a core process to ensure product performance, safety, and mass production stability. Medical injection-molded products, such as surgical instrument handles, catheter connectors, and implant inserts, have extremely high requirements for material biocompatibility, dimensional accuracy, and structural complexity.

However, cracking caused by material, process, or design flaws remains a common challenge in the industry. This article explores the causes, solutions, and preventive measures for cracking in medical injection-molded products.

In today's rapidly evolving medical technology landscape, plastic products, ranging from disposable syringes to complex artificial joints, have become indispensable in modern healthcare. Custom medical injection molding, as the precision manufacturing technology behind this field, is driving the innovative development of the medical industry with its unique advantages, wide applications, and rigorous processes.

In the medical device manufacturing sector, precision injection molding of small medical housings is critical for ensuring equipment performance and safety. These products typically feature micro-scale dimensions, complex structures, and specialized material requirements, imposing stringent demands on molding accuracy, stability, and cleanliness.

From precision electronic components to automotive parts, achieving consistent high-quality production requires a systematic quality assurance framework encompassing equipment, raw materials, mold design, quality control, and workforce competence.

Given the extremely high precision requirements and strict quality control standards for these injection-molded parts, along with the need for excellent service, how to precisely screen out high-quality service precision medical injection molding manufacturers has become an important issue that many medical enterprises urgently need to address.

Surface blurring not only impairs optical effects but may also trigger risks such as microbial growth and abnormal drug adsorption. Based on practices in the medical industry and principles of materials science, this article systematically analyzes the causes of this problem and proposes solutions.

In the field of medical injection molding, poor blanking is one of the key issues affecting product quality and production efficiency. Medical products have stringent requirements for precision, cleanliness, and material properties, so any minor deviation in the injection molding process can lead to serious consequences.

In the field of medical injection molding, poor material ejection stands as a critical issue impacting product quality and production efficiency. Medical products demand stringent requirements for precision, cleanliness, and material performance, rendering even minor deviations in the injection molding process potentially catastrophic.

The article analyzes the causes of burn marks on medical injection-molded products from four aspects: material, process, mold, and equipment. It emphasizes that manufacturers should adopt whole-process control to reduce defect rates.

Although material shortage is caused by a combination of factors including raw materials, molds, injection molding processes, and the environment, such as issues with raw material characteristics and quality, mold design and wear, injection molding parameter settings and temperature control, as well as humidity and temperature fluctuations in the workshop environment, we can address it from the following aspects.

In the process of medical injection molding production, material shortage is a relatively common defect that seriously affects product quality and production efficiency. Medical products have extremely high requirements for the precision, performance, and safety of injection-molded parts.
