Precision Engineering & Machining PREMAK
Engineering & Design
- Machine & Product Design – Development of mechanical machinery, mechanisms, assemblies, production equipment, and engineered products, with 3D CAD modeling focused on functionality, manufacturability, and production requirements.
- 2D Engineering Drawings - Manufacturing drawings with dimensions, tolerances, material specifications, surface-finish requirements and other production information.
- GD&T - Application of Geometric Dimensioning & Tolerancing to communicate functional requirements, datum structures and geometric controls on manufacturing drawings.
- Design for Manufacturing - Engineering designs developed with machining processes, tooling, inspection and production considerations in mind.
