Production Equipment & Manufacturing Capabilities


Aluminum Extrusion Cutting

Shun Teh designs and manufactures its own precision sawing machines, integrated with a high-accuracy servo feeding system to ensure consistent and reliable cutting performance.

Capabilities:

  • Custom aluminum extrusion lengths based on customer specifications

  • Cutting tolerance: ±0.2 mm

  • Minimum cutting length: 8 mm

  • Suitable for high-volume production with stable dimensional accuracy

Deburring

After cutting, all aluminum extrusions undergo a deburring process to remove sharp edges and burrs. This improves product safety, facilitates downstream assembly, and enhances overall part quality.

Brushing

Our brushing process utilizes abrasive belt finishing to create a variety of surface textures according to customer requirements. It is also used to restore or refine surface appearance by removing minor imperfections and handling marks.

CNC Machining

Shun Teh operates 13 CNC machining centers, including machines equipped with 4th-axis capabilities for complex machining requirements.

Using SolidWorks for product design and SolidCAM for CAM programming, we develop optimized machining programs and dedicated production fixtures to ensure efficiency and precision.

Processes include:

  • Drilling

  • Tapping

  • Milling

  • Profile cutting

  • Rough and finish machining

Machining tolerance: ±0.05 mm

NC Machining

Our four NC milling machines are operated by technicians with more than 30 years of manufacturing experience. They are primarily used for:

  • Prototype and sample production

  • Mold-assisted machining

  • Customized fixtures and tooling

  • Secondary machining for production parts

CNC Secondary Processing

Shun Teh is equipped with more than 30 single-axis and multi-axis secondary machining machines for efficient post-processing operations.

Capabilities include:

  • Drilling

  • Reaming

  • Boring

  • Tapping

  • Countersinking

  • Burr removal and hole finishing

These operations improve machining efficiency while ensuring consistent product quality.

Stamping

Our stamping facility includes presses ranging from 15 to 200 tons, available in both standalone and automated production line configurations.

Processes include:

  • Blanking

  • Punching

  • Bending

  • Riveting

  • Press forming

We also provide in-house tooling design, development, and mold manufacturing, enabling flexible production, shorter lead times, and cost-effective manufacturing solutions.

Cleaning

Finished components are cleaned using an ultrasonic washing system to remove machining oils and cutting fluids. Parts are then dried with compressed air and oven baked to ensure they are clean and ready for assembly, surface treatment, or shipment.
