作者: Mike Tang

Hi, I'm Mike Tang, founder of ZetarVac. I have spent more than 20 years in plastics manufacturing, running on-site production, tooling and project evaluation for custom profile extrusion and heavy-gauge vacuum forming. If you need a custom plastic profile or a thermoformed part, send your drawings and I will have our engineers review feasibility, tolerances and tooling before you commit.
