How to finish the production of medical product molds?
The methods used by most domestic medical product mold manufacturers in the finishing stage are generally grinding, electrical processing and fitter processing. At this stage, it is necessary to control many technical parameters such as part deformation, internal stress, shape and position tolerance and dimensional accuracy. It is more difficult to operate in specific production practice, but there are many effective empirical methods. The summary of medical product mold manufacturers includes:
The methods used by most domestic medical product mold manufacturers in the fine production stage are generally grinding, electric production and fitter treatment. At this stage, many technical parameters such as deformation, internal stress, shape and position tolerance and dimensional accuracy need to be controlled. It is more difficult to operate in specific production practice, but there are many effective empirical methods. The summary of medical product mold manufacturers includes:
1. Mold fine manufacturing process control
The production of mold accessories, an overall guiding ideology is to adapt to different materials, shapes and different technical requirements. It has a certain plasticity, through the control of the production, you can achieve good production results.
2. Heat treatment of accessories
The heat treatment process of the accessories requires the accessories to obtain the required hardness, while controlling the internal stress to ensure the dimensional stability of the accessories during production, and the processing methods of different materials are also different. 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, due to the ability to withstand high temperature, quenching using secondary hardening process, 1050-1080 fire, 490-520 high temperature multiple quenching, can obtain high impact toughness and stability, with collapse as the main invalid.
3. Medical product mold manufacturers believe that the quality of the mold directly determines the quality 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 medical device technical indicators, especially in the field of micro medical plastics and other technical fields, domestic equipment technology has been greatly tested. In the face of this fast-growing blue ocean of medical devices, how the main technology of casting molding is consistent with it and seize the opportunity.
4. Accessories grinding
There are three main types of machine tools used for grinding: surface grinding machines, internal grinding machines and tool grinding machines. In the fine production of grinding, to strictly control the occurrence of grinding deformation and grinding cracks, small cracks are also reflected in the subsequent production. Therefore, the polished inlet should be small and large, the coolant should be sufficient, and the parts with a dimensional tolerance within 0.01mm should be ground to a certain temperature as much as possible.
Medical product mold manufacturers believe that it is important to choose the right sand wheel when polishing. For the high vanadium and high molybdenum state of die steel, it is more suitable to use GD single crystal corundum wheel. When making hard alloy and materials with high quenching hardness, diamond sand wheels with organic binder are preferred. The organic binder sand wheels have good self-grinding properties. The rougher the parts after grinding, Ra = 0.2m. In recent years, with the application of new materials, the sand wheel should be trimmed in time in the grinding production to keep the sand wheel sharp. When the sand wheel is passivated, it will slide and squeeze on the surface of the component, which will burn the surface of the component and reduce the strength. The production of plate accessories is mostly made by plane grinding machine, and long and thin plate accessories are often encountered in the production process, which is more difficult to make. Therefore, medical product mold manufacturers feel that during production, due to the adsorption of magnetic force, the parts deform close to the surface of the worktable. After the parts are removed, the parts deform again, and the thickness measurement is consistent, but the parallelism does not meet the requirements. Therefore, the solution can be ground by natural cutting method. When grinding, use contour pads to lay under the parts, and the surrounding blocks are separated. When making, it is a small entrance and multi-light.
