Engineering Support Before Assembly
Before assembly begins, our engineering team reviews product drawings and develops dedicated assembly fixtures, positioning tools and inspection gauges according to each product structure. These tools improve assembly consistency, reduce human error and support stable batch production.
Assembly Fixture Design
Custom fixtures are reviewed for repeat positioning, safer handling and more stable batch assembly.
Positioning Fixtures
Locating tools help operators align parts, holes, brackets, shafts and purchased components consistently.
Inspection Gauges
Simple go/no-go gauges or checking fixtures can be planned for assembly fit and critical positions.
