Custom Plastic Machine Locators for Industrial Automation
Plasticpartsmfg provides precision-engineered plastic machine locators designed for automation lines, jig and fixture assemblies, and industrial equipment. We manufacture components based on your CAD files, focusing on the dimensional accuracy, material durability, and surface finish required for reliable part positioning and workpiece protection.
Whether you are designing a new robotic cell or replacing worn components in an existing assembly line, we provide manufacturing support from initial prototyping to batch production.

Precision Positioning Components
We specialize in producing custom locators that ensure repeatability and stability in high-cycle environments. Unlike metal alternatives, our plastic locators provide non-marring contact, essential for handling sensitive surfaces, fragile electronics, or finished consumer parts.
- Repeatable positioning for high-cycle automated assembly.
- Non-marring contact protects finished and fragile workpieces.
- Wear-resistant grades for conveyor and high-friction zones.
- Dimensional consistency across prototype and batch runs.

Material Selection for Performance
The performance of a machine locator depends on the material's ability to maintain its shape under load. We work with you to select the right grade.
Ask for a Material RecommendationPOM (Acetal)
Excellent dimensional stability and low friction for repetitive positioning.
PEEK
High-performance thermal and chemical resistance for demanding industrial environments.
PA (Nylon)
High impact resistance and durability for heavy-duty stop blocks.
UHMW-PE
Superior wear resistance and low-friction properties for conveyor-line contact surfaces.
Why Choose Plasticpartsmfg for Your Locators
Drawing-Based Execution
We manufacture strictly to your engineering drawings and CAD files, ensuring the tolerances required for your automation system are met.
