Ultra FAST Tooling Program
When you need parts YESTERDAY!

Ultra Fast Tooling (UFT) typically describes a process which either uses high speed CNC, High speed EDM and high speed EDM wire cutting machines.


We are particularly proud of our rapid tooling capabilities, and offer prices well below those typically in charged in the USA.

Advantages of China product development and manufacture extend to a well-established base of local tooling expertise, matching services and quality offered by western tooling firms but with advantages of time and cost savings.
We can respond quickly to requests for quotation after receipt of your CAD (ProE or IGES format) files via email or FTP transfer.


  • Tooling time is much shorter than for a conventional tooling. Time to first articles can be less than one-fifth that of conventional tooling.
  • Tool life is the same as conventional tooling.
  • Tolerances are wider than for conventional tools.

Benifits of Rapid Injection Molding:

  • Prototypes in production material in short timeframes.
  • Allows for full fit and function testing.
  • Discover any design flaws early on. Low cost tooling allows for ease of geometry modification and design refinement.

New! High-Precision Injection Molding Shop

New! High-Precision Injection Molding Shop

Box Enclosures is experienced in providing tooling for high-precision injection molding. This solution is required when molding products with extremely tight tolerances.

Completing your high precision tooling in China is particularly worthwhile as low labor costs allow for an attention to detail that is prohibitively expensive in the West.

We use all modern tooling techniques:

  • Face-mounted inserts for quick change.
  • Regular scheduled tool maintenance.
  • Use of rheologically balanced runners.
  • Use of quick mold change systems.
  • Mold design practices that allow for future flexibility in production.
  • CNC surface grinding
    Obtaining precision dimensions inside cores and cavities across entire tools means that each individual block has to be precisely positioned and aligned within its seat. CNC techniques enable external surfaces to be as flat and square as possible and to be very accurately positioned relative to core and cavity locations.
