Conventionally, metal parts and molding parts were ordered separately from different companies. Our prototype molding department, however, can produce both metal and molding parts together,thus reducing L/T of manufacturing prototypes. In particular, our technology of thin sheet metal processing show an effort for insert molding. As for precise injection molding and insert molding, our exceptional technology and the mold cassette enable the L/T of prototype to shorten. Regarding insert molding, it is the production method that insert metal parts into the mold and to be unified. We can also provide the service that is from producing the injection molding parts and press fit of metal parts and final assembly. By applying our technology and know-how of our original die-sets system for thin sheet metal to our mold technology,we can produce both metal parts and molding parts in-house together. Therefore we can provide the high quality prototype of metal/resin sets without futility and trouble.

From Design and Manufacture Die-sets to Parts-assembly in-house.

Quick Prototyping Metal / Resin Sets ; in 10 days on average.

Shorter deliveries are realized through this system and by our high technics.
Experts in insert molding and outsert molding.
Insert molding is technique that unifies parts by putting metal parts into a resin mold.
The simple mold system applies to resin one. That is why you need not order parts from several companies.
We manage to produce good quality prototypes in minimum time and cost.

Your Problems are...

  • Misfitting metal and resin parts.
  • Fixed lead-times.
  • Take much time for a previous meeting or for procedures to change the design.
  • High costs in case of mismatching in joints.

Our Solution is to Provide a Set Parts.

Good Quality Set Parts Produced with Minimum Cost and Time.

  • Short deliveries.
    In 10 days processing on average.
  • Cost and time-saving with the original simple die-sets system.
  • Flexibility in revising the design and jointing.
    Confirm a jointing while designing dies and produce parts smoothly.



  • Both Metal dies and molding molds are manufactured in-house.
    During jointing, either die / mold will be adjusted.
  • A set order enables to confirm jointing by CAD quickly.
    And that makes to move into production rapidly.
  • All process which will be done in-house enables to launch products onto the market rapidly.
