Cost-Effective ABS Assembly Fixtures | CNC Machined for Electronics Manufacturing

Tagged: CNC Milling ABS CNC

We successfully delivered a cost-effective ABS assembly fixture for a consumer electronics manufacturer. Machined from ABS (acrylonitrile butadiene styrene), this custom fixture provides precise component positioning during manual assembly operations. The design features precision-milled locating pockets, guide pins, and ergonomic handling features — all at a fraction of the cost of metal or high-performance plastic alternatives.
