Unlike ordinary industrial moulds, medical moulds must meet stringent standards such as biocompatibility, corrosion resistance, and high precision, resulting in significant differences in their cost composition and calculation methods. This article will systematically analyze the cost calculation logic of medical moulds from three dimensions: cost composition, quotation methods, and industry practices.

Precision medical injection molding, as the core process in medical device manufacturing, directly determines the life safety and treatment efficacy of patients. From pacemaker housings to minimally invasive surgical instruments, from medical catheters to biosensor bases, every precision injection-molded part must meet stringent standards in terms of dimensional accuracy, surface quality, and biocompatibility.

Medical injection-molded products, due to their direct contact with the human body or use in precision medical scenarios, impose stringent requirements on surface quality. Surface defects such as flow marks, silver streaks, gas marks, weld lines, and sink marks not only compromise appearance but also risk bacterial growth or structural weakness, directly threatening patient safety.

Medical injection molding faces challenges from uncontrollable factors like material variability, environmental shifts, and equipment issues, leading to defects. This article proposes solutions such as enhanced quality control, environmental regulation, and smart equipment upgrades, supported by a case study, to improve production efficiency.

Given the medical industry’s stringent requirements for biocompatibility, sterility, and long-term stability, mold manufacturing demands rigorous control across design, materials, and processes. This article explores three critical considerations: mold design, material selection, and manufacturing processes.

Hot runner system has become the core equipment for manufacturing high-precision medical products due to its ability to improve efficiency and reduce waste. However, the problem of glue leakage has long plagued the industry. Glue leakage not only leads to mold damage and production interruptions but may also directly affect the safety of medical products due to glue contamination.

However, deformation during heat treatment has long been a significant challenge plaguing the industry. Deformation not only affects the precision and service life of the mold but may also directly lead to a decline in the quality of medical products.

Medical injection-molded products may whiten, affecting quality and safety. Causes include material issues, improper process parameters, and mold problems. Solutions involve optimizing material management, adjusting processes, improving molds, and strengthening quality control.

In the medical field, a mold for a cardiac stent may be worth hundreds of thousands of yuan, and a set of tumor radiotherapy positioning molds can easily cost several thousand yuan. Behind these seemingly "exorbitant" figures lies the ultimate protection of human dignity in the medical mold industry.

Compared to ordinary industrial molds, medical molds must meet stricter standards, particularly in terms of precision, material compatibility, cleanliness, and regulatory compliance. This article explores the four core requirements for medical injection mold processing based on industry needs, helping practitioners grasp key technical points.

From precision syringe components to complex surgical instrument casings, medical injection molding manufacturers ensure that every product meets strict medical standards through a series of rigorous and standardized production processes. Let's take an in-depth look at the production processes of medical injection molding manufacturers.

By adopting advanced technologies such as high-precision temperature-controlled molds, multi-stage injection processes, and online quality inspection, combined with the ISO 13485 quality management system, the surface quality of medical products can reach a mirror finish (Ra ≤ 0.1 μm) and meet the requirements of FDA, CE, and other international certifications.
