Staple pins for plastic welders Silver 500 pcs mix, model 11867

Pack of 500 mixed staple pins by Silver designed for use with plastic welders. These metal staples are intended to reinforce and repair thermoplastic materials during hot-plate or ultrasonic plastic welding and are compatible with standard staple-fed plastic welding tools. The set contains a mix of staple sizes suitable for common repair tasks on plastic bumpers, fenders, housings and other molded plastic parts used in automotive, industrial and workshop environments.

Advantages

Metal construction provides mechanical reinforcement to welded joints and cracks, improving structural integrity of repaired thermoplastic parts. A mixed pack of 500 staples reduces the need to purchase multiple size-specific packs and supports a variety of repair scenarios. Staples are designed for straightforward insertion with compatible plastic welding tools and heat-assisted processes, allowing fast, repeatable repairs.

Suitable for

• Repairing cracked or torn thermoplastic car bumpers and fenders
• Reinforcing joints in molded plastic housings and panels
• Workshop and industrial plastic repair where mechanical fastening is needed
• Professional and hobby use with compatible plastic welding tools

When it may not be suitable

These metal staples are intended for use with thermoplastic materials that can be welded and reinforced by mechanical fasteners. They are not suitable for thermoset plastics or composite materials that cannot be softened and welded. Also, they are not designed as a final cosmetic solution where visible fasteners would be unacceptable without further finishing.

Key specifications

• Contents: 500 mixed metal staples
• Material: metal suitable for mechanical reinforcement during plastic welding
• Intended use: reinforcement and mechanical fastening of thermoplastic parts
• Compatibility: designed to work with staple-fed plastic welding tools and heat-assisted welding processes

How to use

Prepare the damaged area by cleaning and, if required, grinding or trimming rough edges to create a flat surface. Heat the plastic welding tool to the recommended temperature for the specific thermoplastic material, then insert a staple into the tool's feed or holder according to the tool instructions. Press the staple into the softened plastic across the crack or joint so the staple legs penetrate both sides and draw together. After cooling, clip or file any excess staple protrusion and finish the surface as needed before painting or sealing.

What to consider before purchase

• Verify compatibility of staple dimensions with your plastic welding tool and staple holder
• Ensure the target plastic is a weldable thermoplastic rather than a thermoset or composite
• Consider whether a mixed pack meets your size needs or if specific staple sizes are required

Usage recommendations

For best results, practice on scrap material to set appropriate tool temperature and insertion depth, and always follow the plastic welder manufacturer’s safety and operating instructions. After mechanical reinforcement, use appropriate fillers and surface treatments to restore appearance if required.
