• Multiple Material Options: Available in carbon Steel, stainless Steel, aluminum, and brass.

• Strong Thread Retention: Ideal for improving thread strength in softer materials like plastic or wood.

• Versatile Applications: Suitable for metal thread repair, 3D printed parts, and industrial assemblies.

• Custom Manufacturing: Tailored to your dimensions, materials, and surface finishes.

• Durability: Excellent resistance to vibration, torque, and mechanical stress.

Manufacturing Process

Our metal thread inserts are manufactured using precision CNC machining, turning, milling, and heat treatment processes.
Each insert undergoes strict process control to ensure stable thread geometry, smooth surface finish, and consistent quality. The inserts can be produced in large or small batches according to customer requirements, ensuring both flexibility and cost-efficiency.

Material Selection

• Carbon Steel: Offers high tensile strength and cost efficiency; suitable for heavy-duty applications.

• Stainless Steel: Provides excellent corrosion resistance and durability, ideal for marine and outdoor environments.

• Aluminum Alloy: Lightweight and corrosion-resistant, perfect for aerospace and lightweight assemblies.

• Brass: Commonly used for metal thread inserts for plastic and 3D printing, providing excellent heat conductivity for heat-set installation.

Surface Treatment Options

We provide a variety of surface finishing processes to enhance corrosion resistance, wear resistance, and appearance:

• Polishing – For smooth and shiny surfaces.

• Electroplating (Nickel, Zinc, or Chrome) – Enhances corrosion protection.

• Anodizing – Suitable for aluminum inserts, improving hardness and surface aesthetics.

• Passivation – Increases stainless steel durability and chemical resistance.

Precision & Quality Control

Our production process follows strict ISO quality standards.

• Tolerance Control: ±0.01 mm

• Surface Roughness: Ra 0.8 or better

• Inspection Equipment: Coordinate Measuring Machine (CMM), thread gauges, surface roughness testers, and optical comparators.
  Each metal thread insert is 100% inspected before shipment to ensure consistent quality and performance.
