What Is a Plastic Insert?

 

 

Plastic inserts are plastic functional components installed via pressing or clipping into substrates, designed for component connection and assembly in products such as furniture, casters, metal tubes, and industrial equipment.

 

Benefits

Secure Connection

Plastic inserts fill installation gaps, ensuring a secure connection between the caster and the column, preventing wobbling and detachment.

Double Protection

Reduces caster vibration and impact, avoids direct contact between metal parts, and protects pipes and casters from wear and odor.

Lightweight Design

Lighter than metal inserts, reducing equipment load and saving on raw materials and bulk purchasing costs.

Easy Installation

No complicated tools required; simply press the plastic insert into place or clip it in place, compatible with various caster installation needs.

 

Application

  • Furniture Frames

    Plastic inserts are used for chair, table, and cabinet frames, enhancing structural stability while protecting the ends of metal or wooden tubes.

  • Casters & Leveling Feet

    Used in caster and leveling foot installations, plastic inserts provide a secure mounting base, improving connection strength and preventing loosening over time.

  • Metal Tube Assemblies

    Plastic inserts ensure a tight fit in both round and square tube assemblies, reducing wear and maintaining reliable connections.

  • Industrial Equipment

    For machinery and support structures, plastic inserts help maintain long-term assembly stability and consistent performance under load.

Q: What trade terms do you use?

A: We normally quote based on FOB Taiwan. Other trade terms can be arranged upon request if confirmed in advance.

Q: What is the use of plastic pipe inserts?

A: Plastic pipe inserts provide rigid support within the pipe fitting, preventing leaks, accidental disconnections, and maintaining the structural integrity of the connection.

Q: How to install inserts in plastic?

A: Place the insert above its cavity, keep it straight and centered, then apply slight pressure while heating. Once the insert reaches the plastic melt temperature, it will embed into the part.

Q: What materials are used for plastic inserts?

A: Common materials include thermoplastics (PP, Nylon/PA, PC, ABS, PE, Acetal), thermosets (Polyester, Epoxy, Melamine, Urea resins), and elastomers (Polyurethane, natural rubber).

Q: Why are pipe inserts necessary?

A: Pipe inserts maintain pipe rigidity under side loads, ensure an effective seal with O-rings, and prevent deformation or leaks, especially in press-fit pipe systems.

Q: Can plastic inserts be customized?

A: Yes. Plastic inserts can be customized in material, dimensions, thread type, and installation structure to suit different tube sizes, load requirements, and industrial applications.
