diaphragm seals deburring, turning lines removal and polishing technology method of rubber and plastic product parts

How to deburr,deflash,remove turning lines of rubber, plastic diaphragm seal parts?

The diaphragm seal is a key component of pneumatic pumps and valves, diaphragm pump valve bodies and other products. Its main function is to perform the sealing function. It has been widely used in petrochemical, electric power, aviation, machinery and textile, medical and other industries. The main materials are PTFE polytetrafluoroethylene, Teflon and other polymer materials. There are slight burrs and turning lines in the production process, which will affect the sealing performance of the product. How to mechanically remove burrs and turning lines on the surface and reduce the roughness is a very troublesome problem. In this case, we will share a PTFE sealing diaphragm product high-efficiency deburring, removal of turning lines to reduce the surface roughness of the process technology and method. This finishing process solution is also suitable for deburring, deflashing and polishing of polymer products made of other materials such as polyester and resin.

5. Additional instructions
  • The burrs on the surface of the sealing diaphragm are relatively slight, but the turning tool lines are very deep. The rough finishing and polishing machine uses a special polishing machine for plastic products. Rough grinding uses coarse-grained abrasives media to achieve the effect of removing burrs and turning tool marks.
    Fine polishing uses precision finishing ceramic media with micro-cutting force and fine-grained tumbling media, which can further reduce the surface roughness.
  • After fine polishing, use an automatic separating machine to separate the product from the abrasive media, and then use a dryer to dry it after cleaning.

6. Final summary
  • In this case, we demonstrate the process solution of automated deburring, removing turning tool lines and polishing of a PTFE polytetrafluoroethylene sealing diaphragm product.
  • If you need professional technical support for the deburring, deflashing, removal of turning tool lines and polishing of PE polyethylene, PA polyamide, PP polypropylene, polytrifluoroethylene, polyvinylidene fluoride and plastic, rubber and other polymer material product parts or the following plastic accessories, you can refer to the above cases:

Deburring, deflashing and polishing technology of laptop middle frame, bezel, chassis of magnesium-aluminum-zinc alloy die-casting parts

How to deburr, deflash, descale, polish magnesium alloy laptop frames of digital product parts?

Among the parts of digital products such as mobile phones, laptops, digital cameras, and tablet computers, the middle frame, bezel, chassis, shell are mostly made of soft metal materials such as aluminum alloy, magnesium alloy, and zinc alloy through die-casting and then CNC precision machining. These metal structural parts often produce burrs, turning lines, and stains during the production process. Therefore, the automated precision finishing and polishing process of the product surface is particularly important. In this case, we will share a magnesium alloy laptop component – the middle frame structure of the automatic high-efficiency deburring, descaling, polishing and brightening process technology and method. This finishing and polishing process solution is also suitable for the deburring, flash removal, burnishing of other soft metal machined parts such as aluminum alloy, zinc alloy, and copper alloy.

5. Additional instructions
  • Aluminum-magnesium alloy frame, bezel, chassis is an important part of electronic digital products. Due to its light and soft material, and the complex and special-shaped parts such as holes, gaps, and corners on the surface, the dimensional accuracy is high. Therefore, the cutting force for removing burrs, flash and oxide scale should not be too heavy, and the complicated body of parts should be fully polished. Therefore, the polishing machine adopts rectangular tub finisher, and small-sized tetrahedron-shaped plastic media is used for rough finishing, mixed with large-sized cone-shaped polyester media, the sharp angle of the plastic media can reach deep into the grooves and corners to remove burrs and oxide layers.
    Fine polishing uses precision ceramic polishing media without cutting force, spherical porcelain polishing media, which has a high density and has a polishing and brightening effect, which can further reduce the surface roughness.
  • In order to improve the anti-rust performance of the product after water treatment, use a vibratory drying machine with corn cob polishing media to absorb moisture and dry the inner and outer surfaces.
