TDC’s precision processing for resins

TDC offers precision processing service for resin,

Features of TDC’s precision machining for resins

Although many have voiced concerns such as the inability to achieve precision when compared to metal processing, resin is now becoming an indispensable material in the semiconductor, automotive, and machine tool industries. TDC’s resin processing technology, which we have cultivated over the years, can solve any precision or shape resin processing problems.

TDC’s resin precision processing has the following strengths and features.

  • High-precision polishing
    Our precision polishing technology enables ultra-high-precision metal precision machining at the micron and nano-level by controlling the amount of removal. Compared to machining methods such as cutting and grinding, TDC can handle any shape without placing a load on the object.
  • Quick delivery and express delivery are possible.
    With more than 100 polishing machines, we can provide quick delivery even for large lots and complex processing.
    For urgent cases, we can also provide “express response” services.
  • Please feel free to contact us for
    TDC takes small lot orders from one piece, or for prototype production.
  • Owns a wide variety of over 100 processing
    TDC owns over 100 processing machines such as lapping and polishing machines, surface grinders, and other polishing equipment.
    We also have a variety of CNN, milling machines, and other machining equipment to handle all types of processing.
    About half of the more than 100 polishing machines are manufactured in-house, enabling “low cost” and “high quality” manufacturing.
Feel free to contact us for any inquires.

Materials

We perform precision processing of resins using all the processing technologies in which we excel, such as polishing, cutting, and grinding. Typical resins that can be handled are as follows

  • Engineering plastics
  • Acrylic
  • Teflon and other coatings

Importance of Resin Precision Machining

Resin materials are attracting a great deal of attention as alternative materials to metal to reduce body weight in electric and electric vehicles, which are now becoming the mainstream. In addition to the actual adoption of resin-based parts, precision processing technology for resins is becoming increasingly important, coupled with advances in engineering plastics and resin-to-metal bonding technology. With the development of recycling technologies and biodegradable plastics, the demand for resins is expected to grow even more in the future. If you are considering precision processing of resin, please feel free to contact us.

Example of TDC’s resin precision machining

Here are some examples of typical precision machining of resins at TDC.

Mirror processing and test piece fabrication of various resin substrates

  • Materials: Engineering plastics, Acrylic, Polycarbonate, Teflon coating, etc
  • Processing details: Surface roughness of less than 5 nm can be achieved for most resin materials.

Mirror finishing can be applied to various resin materials, including polishing of all engineering plastics, acrylic, polycarbonate, and Teflon coated films. In addition, the finished surface roughness of resin materials generally varies greatly depending on the material, but it is possible to achieve a surface roughness of less than 5 nm for most materials. For details, please refer to the “What is the surface roughness“.

High precision shim and gauge of polyimide resin

Compared to metals and ceramics, resin is an extremely soft material that is generally considered difficult to process with precision. However, TDC’s polishing technology, which we have cultivated over the years, makes it possible to produce high-precision shims and gauges with minimal sagging and warping, even with resin materials.

Please feel free to consult with us for suggestions on appropriate materials, not limited to polyimide, depending on the environment and specifications of your application.
