Medical products mold precision requirements are high, how to protect
The methods used by most domestic medical product mold manufacturers in the finishing stage are generally grinding, electrical processing and fixture processing. At this stage, it is necessary to control many technical parameters, such as part deformation, internal stress, form and position tolerance and dimensional accuracy, which are more difficult to operate in specific medical product mold production practice, but there are a variety of effective empirical methods, including:

Process Control of Medical Product Mold Finishing
For the processing of mold parts, an overall guiding ideology is to adapt to different materials, shapes and different technical requirements. It has a certain degree of plasticity, and good processing results can be achieved through the control of processing.
According to the appearance of the parts, the parts can be roughly divided into three categories. Shafts, plates, special-shaped parts and other typical processes are rough machining 3354 heat treatment (quenching, quenching) 3354 finishing 3354 electrical machining 3354 clamp (surface treatment) 3354 group processing.
Medical Products Mold Parts Heat Treatment
The heat treatment process of the parts requires the parts to obtain the required hardness, while controlling the internal stress, ensuring the dimensional stability of the parts during processing, and performing different treatments on different materials. In recent years, with the development of the mold industry, the types of materials used have increased. In addition to Cr12, 40Cr, Cr12MoV, hard alloy, you can also choose some high-strength, strong convex, mold, new material powder alloy steel (such as V10, ASP23, etc.).
For V10, APS23 and other powder alloy steel parts, can withstand high temperature tempering, so quenching with the second hardening process, 1050-1080 fire, 490-520 high temperature multiple immersion, can obtain higher impact toughness and stability, the main failure powder alloy steel manufacturing price is higher, but its performance is good, there is a trend of widespread use.
The quality of the medical product mold directly determines the pros and cons of the product. In the field of medical devices, molds affect the quality and productivity of medical devices at the same time. However, with the improvement of technical indicators of medical devices, especially in advanced technical fields such as micro-precision medical plastics, domestic equipment technology has been greatly tested.
Medical Products Mold Grinding Parts
There are three main types of machine tools used for grinding: surface grinding machines, internal cylindrical grinding machines and tool grinding machines. Grinding process to strictly control the occurrence of grinding deformation and grinding cracks, small cracks also appear in the follow-up processing. Therefore, the polishing inlet must be small and large, the coolant must be sufficient, and the parts with a dimensional tolerance within 0.01mm must be ground to a certain temperature as much as possible. It is important to choose the right grinding wheel when polishing. For the high vanadium and high molybdenum state of die steel, it is more appropriate to use GD single crystal corundum wheel. When processing hard alloy and high quenching hardness materials, the diamond grinding wheel with organic binder is preferred. The organic binder grinding wheel itself has good abrasion resistance. The rougher the workpiece after grinding, Ra = 0.2m. In recent years, with the application of new materials for medical product molds, the grinding wheel should be trimmed in time to maintain the sharpness of the grinding wheel. If the grinding wheel is passivated, it will slide and squeeze from the surface of the workpiece, causing burns on the surface of the workpiece and reducing the strength.

On May 20, 2023, Xinyu launched an outdoor expansion activity with the theme of "Cohesion to Win the Future" in Anji Zhuhai. Through the development of the activity, the cohesion and overall centripetal force of the employee group were enhanced, and the positive communication between employees was established., Mutual trust, unity and cooperation, cultivate team awareness, and increase the sense of responsibility of employees. One by one well-designed team building games aroused everyone's strong interest and enthusiasm. In the process of cross-game experience, the team members won one by one with the cooperation. This activity not only enhanced the cohesion between Xinyu employees, but also cultivated a tacit understanding between each other.
2023/9/21, the launching ceremony of the digital supply chain platform of Wujiang Xinyu Precision Mould Co., Ltd. was solemnly held in Suzhou Taihu International Conference Center. Gan Xiangquan, general manager of the company, spoke on behalf of Xinyu Company. Since then, the company has officially taken a big step towards a new model, a new journey and a new future!
Plastic mold design and manufacturing personnel must carefully carry out mold design according to the above basis and requirements provided by customers. When designing molds, the above contents should be specified one by one and expressed in the form of drawings and technical documents. Then let's learn about the detailed operation of the general procedures for plastic mold design and manufacturing!
