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, However, some need high requirements in parallelism, perpendicularity, centrality, and accuracy! such as in the electronic and semiconductor industry, the accuracy needs to reach +/-0.001mm
Typically,our manufacturing workshop prefer to choose the qualified carbide and hard steel to produce the custom punch and die tooling components. Compared with steel, carbide has higher hardness and strength, which significantly extends the service life of your tools. Our comprehensive range of custom punch tools and punch tooling components has wide applications in various industries.
Therefore, state-of-the-art machining equipment and technology are very critical. They are used 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.
