Ultra Tight Tolerance (.0005 - .001)
Knapp Mfg. has been synonymous with precision since Fred Knapp founded the company in 1945. Our team is capable of building SPI class 101 tools and molding parts that hold tolerances as +/- .0005 of an inch. We currently run over 100,000,000 (yes - one hundred MILLION) parts a year with this tolerance on critical features of customer products.
The standard Plastic Injection Molding tool produced by Knapp Mfg. is built to SPI Class 101 standards. This is the highest class tooling available with fully inserted and hardened cavities and cores. We warranty these tools to run one million cycles or more.
In-house Maintenance & Repair
Even the best made SPI Class 101 tools need maintenance to live up to the one million + cycle expectation we have for our tools. With our fully stocked and staffed tool room we maintain, modify to customer specification, or repair tooling without having to “send it out.” This allows us to maintain control of the tools while saving time in the process. Our tool room has modern Die-Sinker EDM capability, as well as CNC machining capability.
