Mold Design & Rapid Prototyping
Manville Rubber Product'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. Design and build quality varies greatly with the knowledge, experience and commitment of the molder responsible. Perfectly dimensioned finished parts begin with 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.
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.
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.
Custom Rubber Compounding
Rubber vulcanization is a unique process. To insure total control and traceability over the manufacturing process and output, MRP develops all compounds in-house. This allows us to:
Develop compounds that meet specific, often challenging performance specifications.
Fine-tune elastomer properties as a project evolves over time identify substitutions or adjustments when raw material prices increase.
Adjust the compound to improve production without sacrificing quality or compliance.
Minimize lead times, particularly when working with government mandated certifications.
