Trim Tool and form dies
In the metal stamping industry, punch tooling and dies are widely used to press the material into different shapes or cuts. Some are not precise because of the end-products needs, but some need high requirements in parallelism, perpendicularity, centrality, and accuracy! Especially in the electronic and semiconductor industry, the accuracy needs to reach +/-0.001mm.
Typically carbide or hard steel are used to make the custom punch tooling components. Compared with steel, carbide has higher hardness and strength, so it significantly extends the service life of your tools. Our comprehensive range of punch tooling components has wide applications in various industries.
Therefore, state-of-the-art machining equipment and technology are very critical. They’re applied to ensure consistent quality, high precision, and excellent working performance. Also, the TICN and DLC coating are available to extend the tool life and improve the end-part quality.
