In the booming medical industry, the quality and safety of medical products are directly related to the lives and health of patients. Medical precision moulds, as a crucial link in ensuring the quality of medical products, are of utmost importance. From reagent boxes, reagent strips, and minimally invasive medical components to various precision medical device parts, all rely on high - quality moulds to achieve their precision and safety. However, in reality, many enterprises, due to insufficient attention to several key early - stage links in the development of medical precision moulds, have fallen into the dilemma of "post - remedy", which not only leads to a significant increase in costs but may also seriously affect product quality and production progress.

Pain Points Frequently Occur Due to Neglecting Key Links

Improper Selection of Steel Materials, Hiding Quality Risks

Steel materials can be regarded as the "skeleton" of moulds, and their selection has a decisive impact on the performance and service life of moulds. Some enterprises, in order to reduce costs, choose pre - hardened steel materials for precision mould manufacturing, ignoring their high susceptibility to wear during the production process. Pre - hardened steel materials have insufficient strength, and long - term use can lead to the collapse and deformation of the parting surface, seriously affecting the precision of the mould, and in turn causing a series of problems such as dimensional deviations and appearance defects in medical products. Taking some transparent plastic products as examples, such as PC, PMMA, and PS, if S136 fully hardened stainless steel is not selected but inappropriate steel materials are used, the polishing effect will be greatly compromised, the surface of the mould will be rough, which not only affects the transparency of the products but also makes post - maintenance extremely difficult. In severe cases, re - moulding may be required, resulting in huge time and cost wastage.

Rough Machining Processes, Difficult to Guarantee Precision

The machining process is the key to achieving mould precision. Fast - wire electrical discharge machining (EDM), ordinary spark machines, and low - precision CNC machines are prone to dimensional deviations in moulds during the machining process due to their limited precision. Some enterprises, in an attempt to save machining costs, choose rough machining processes. When dimensional problems arise, they try to make up for them through manual "fitting". However, this method is extremely inefficient and can far from meet the requirements of precision moulds, ultimately leading to mould scrap.

Unreasonable Product Structure Design, Increasing Mould Difficulty

In the early stage of product research and development, if the understanding of the needs of medical products is not deep enough, it will lead to an unreasonable product structure design, which in turn imposes excessively high requirements on the precision of the mould. For example, some medical product designs have complex structures and narrow spaces, forcing the mould to possess extremely high precision, which undoubtedly increases the difficulty and cost of mould development. At the same time, an excessive pursuit of high precision while ignoring actual usage requirements can also lead to over - control of quality during the production process, resulting in a waste of resources.

Full - Process Control to Create High - Quality Moulds

Accurate Selection of Steel Materials, Laying the Foundation for Moulds

Selecting appropriate steel materials based on the product structure and plastic characteristics is the first step in creating high - quality moulds. For medical precision moulds, giving priority to fully hardened steel materials is a wise choice. Although rough and precision machining of fully hardened steel materials need to be carried out separately, the machining cost is similar to that of pre - hardened steel materials, but it can effectively avoid the problems of wear and deformation caused by pre - hardened steel materials. For transparent plastic products such as PC, PMMA, and PS, it is essential to insist on using S136 fully hardened stainless steel to ensure that the steel materials have good polishing performance, improve the transparency of the products, facilitate post - maintenance of the moulds, and extend their service life.

Optimizing Machining Processes to Ensure Mould Precision

During the machining process, selecting high - precision machining equipment is crucial. Slow - wire EDM has higher precision compared to fast - wire EDM and can fully meet the dimensional requirements of precision moulds. High - precision spark machines and CNC machines can ensure the surface roughness and dimensional precision of the moulds. By adopting advanced machining equipment and processes, dimensional deviation problems can be avoided from the source, the number of post - manual correction steps can be reduced, and the production efficiency and quality of moulds can be improved.

Optimizing Product Structure to Reduce Mould Costs

In the early stage of product research and development, it is necessary to have an in - depth understanding of the needs of medical products and work closely with the design team to optimize the product structure. Through reasonable structural design, excessively high requirements for mould precision can be avoided, and the difficulty and cost of mould development can be reduced while meeting the product's functions and quality requirements. For example, simplifying complex structures and reasonably designing demoulding angles can not only ensure the smooth production of products but also reduce the workload and cost of mould machining.

Strengthening Project Management to Control Full - Process Quality

Good project management is the key to the success of medical precision moulds. It is necessary to form a project team with a full - process knowledge system to strictly control each link from product structure design, steel material selection, machining processes, to production quality control. The project team should have an in - depth understanding of customer needs, coordinate the cooperation among various departments, and promptly solve problems that arise during the development process to ensure that the mould development proceeds smoothly according to the plan and that the mould quality meets the requirements.
