How we can help
We fully understand the impact that tolerance management has on your product assembly process and ensure that the service we provide is of the highest standard.
Ability to validate tools in-house using our 3D CMM.
Internal tool design
Our plastic injection tool manufacturing engineers have a complete checklist that they use for every tool design and tool manufacturing. We are able to make P20 or H13 steel tools at 1/3 to 1/2 the cost of other countries' aluminum tools.
Therefore, in order to better serve our customers and provide better products, we started producing steel tools exclusively around the world. With a more efficient system, we can make steel tools in the same time as aluminum tools while delivering a better finished product at a lower cost.
