Outstanding tooling design and fabrication are critical to the success of your new project. Manville's experienced staff have the skill and passion for detail that insures your tooling investment is designed and produced to the highest standards of accuracy, quality, and durability . Customers choosing a custom molding supplier for their next new project should be aware that not all tooling is created equal and design and build quality can vary greatly with the knowledge, experience and commitment of the molder responsible. Perfectly dimensioned finished parts cannot be made without perfect tooling.

Manville offers you the following assurances with every new tooling project:

  • Tooling is designed in house by Manville experts and incorporates the best and latest concepts drawn from the unparalleled rubber molding technical expertise for which we are known
  • Tooling is fabricated using the best mold making steel grades selected based upon the complexity of the mold design and expectations for production demand . Most molds will be fabricated using P20 or 4140HT tool steel for long term durability. For short run projects only, we can use carbon steel grades 1030-1050 for cost efficiency.
  • Rubber vulcanization is a unique process and to insure total control over the process Manville validates all new tooling and processing parameters before any sample parts are submitted to the customer.
    • Numerous production trials are used to dial in molding parameters
    • pilot parts are dimensionally verified against part drawings with results permanently logged into our mold files and maintained for the life of the mold
    • parts are destructively tested to verify the process has been properly established and is in control.
    • once validated, materials and process parameters are locked into our unique Work Instruction system. Critical parameters can be easily recalled for every mold, every time a production run is required which yields consistent results every order.
  • New sample parts can be submitted with PPAP level dimensional reporting and material certification, as required
  • Tooling, once paid for, is customer property. Customers should be wary of any suppliers that instead of tooling charges try to pass off "setup charges" which fail to provide the customer with rights of tooling ownership.
