Product Description
CNC Machined Plastic Parts | Precision Custom Components
Product Overview

At JYH CNC Precision Machining Company, we manufacture CNC machined plastic parts for applications requiring accurate dimensions, complex geometries, lightweight construction, and reliable mechanical performance.

Unlike molded plastic components, CNC machining allows plastic parts to be produced directly from solid engineering plastic materials without requiring injection molding tooling. This makes CNC machining an excellent solution for prototypes, low-volume production, customized components, and complex precision parts.

We manufacture custom plastic components according to 2D engineering drawings, 3D CAD models, and technical specifications, with options for dimensional inspection, surface finishing, and assembly.

CNC Plastic Machining Capabilities

Our CNC machining equipment can produce a wide range of customized plastic components, including:

  • Precision plastic housings
  • Enclosures and covers
  • Bushings and spacers
  • Gears and mechanical components
  • Insulating components
  • Mounting brackets
  • Sealing components
  • Structural plastic parts
  • Custom engineering plastic components
  • Complex prototype parts

Depending on the component design, we can use CNC milling, CNC turning, drilling, tapping, boring, and other precision machining processes.

Engineering Plastics We Machine

We work with a variety of engineering plastics selected according to mechanical, thermal, electrical, and chemical requirements.

PEEK

PEEK is a high-performance engineering plastic known for its excellent chemical resistance, dimensional stability, mechanical strength, and temperature resistance. It is suitable for demanding industrial, medical, electrical, and precision applications.

Polycarbonate (PC)

PC provides a combination of impact resistance, dimensional stability, and electrical insulation, making it suitable for electronic and industrial components.

PA / Nylon

Nylon offers good mechanical strength, wear resistance, and relatively low weight. It is commonly used for bushings, gears, guides, and other mechanical components.

ABS

ABS is suitable for general-purpose mechanical components and prototypes where good machinability, toughness, and cost efficiency are required.

PMMA

PMMA provides good optical clarity and weather resistance and can be CNC machined for transparent or translucent components.

Other engineering plastics can also be processed according to customer requirements.

Advantages of CNC Machined Plastic Parts
No Injection Mold Required

For prototypes and low-volume projects, CNC machining can eliminate the need for dedicated injection molds, helping reduce initial tooling costs and shorten development time.

High Dimensional Accuracy

CNC machining allows tight control over critical dimensions, holes, slots, threads, and mating surfaces.

Complex Geometries

CNC milling can produce detailed features and complex three-dimensional shapes that may be difficult to manufacture using conventional plastic fabrication methods.

Suitable for Prototypes

Design changes can be implemented quickly without modifying an injection mold, making CNC machining suitable for product development and functional testing.

Wide Material Selection

Different engineering plastics can be selected according to the component's strength, wear resistance, chemical resistance, temperature requirements, electrical properties, and weight.

CNC Machining Process

Our typical production process includes:

1. Drawing & CAD Review
Our engineers review the design, material, tolerances, and machining requirements.
2. Material Preparation
The selected engineering plastic is prepared according to the required dimensions and specifications.
3. CNC Machining
Milling, turning, drilling, tapping, and other operations are performed according to the CAD model.
4. Deburring & Cleaning
Machined edges are carefully deburred and the components are cleaned.
5. Inspection
Critical dimensions and functional features are inspected according to the drawing.
6. Assembly & Packaging
If required, components can be assembled with other metal or plastic parts before final packaging.
Applications

CNC machined plastic parts are widely used in:

  • Electronics
  • Robotics
  • Industrial automation
  • Medical equipment
  • Semiconductor equipment
  • Power conversion equipment
  • Electrical systems
  • Automotive equipment
  • Aerospace
  • Laboratory equipment
  • Precision machinery
  • Custom mechanical assemblies
Metal & Plastic Assembly

For projects requiring multiple materials, we can combine CNC machined plastic components with precision metal parts and provide assembly services.

For example, a finished assembly can include:

CNC Aluminum Parts + Stainless Steel Components + CNC Plastic Parts + Fasteners → Complete Mechanical Assembly

This provides customers with a convenient manufacturing solution from individual components through final assembly.

Quality Control

Quality inspection is performed according to customer drawings and technical requirements. Depending on the project, we can provide:

  • CMM dimensional inspection
  • Critical dimension inspection
  • Material certification
  • Surface inspection
  • Dimensional inspection reports
  • First Article Inspection
  • Assembly inspection

Special attention can be given to critical features such as holes, threads, flatness, wall thickness, mating surfaces, and overall dimensions.
