Manufacturing and Fabrication of Plastic Angles
Plastic angles are typically produced via extrusion, machining, or injection molding. Extrusion allows for continuous lengths with uniform cross-sections, while machining is suitable for custom cuts and detailed features. Suppliers like www.carlisleplastics.com and www.usplastic.com offer a range of stock and custom options.
Cutting and Joining Techniques
- Cutting: Use saws designed for plastics; cutting speeds should be optimized to prevent melting.
- Joining: Adhesives, mechanical fasteners, or welding (for certain plastics) ensure secure assembly.
- Finishing: Filing, sanding, or thermal shaping can refine edges and fitments.
Maintenance and Durability Considerations
Plastic angles require minimal maintenance, primarily cleaning with mild detergents. UV stabilizers can extend service life outdoors. Regular inspections for cracks or deformation help ensure safety and longevity.
