Plastic Injection

Plastic Mold Development:
Plastic injection molding
With 40 years of experience in precision injection molding, we offer one-stop solutions from mold design to mass production. We possess complete plastic injection molding manufacturing capabilities, providing end-to-end services for various industrial, medical, safety, and electronic products, from design and development, mold making, injection mass production to assembly and testing.
professional strength
professional team
The injection engineering team has 10-25 years of industry experience and provides professional technical support.
Advanced equipment
Available in multiple models ranging from 30 tons to 450 tons, including micro injection, gas-assisted, and water-assisted technologies.
Automated production
Equipped with robotic arms, a drying and dehumidification system, and a central feeding control system.
Precision testing
3D measuring instrument, 2.5D projector, surface roughness and dimensional inspection

We are skilled in handling various materials, such as ABS, PC, PA66, PBT, TPE, PMMA, PC+ABS, and POM, and can provide material recommendations and optimization solutions based on product structure and application.

Practical experience
From industrial parts to medical devices, we have accumulated experience in over 3,000 types of injection-molded products.
Safety protection products
Professional protective equipment components such as alarm housings, reed sensors, monitor housings, and explosion-proof enclosures.
Automotive electronics
Automotive electronic components such as wire module housings and power-off brake kit mounting brackets
medical equipment
Medical equipment components such as the control module housing of the electric medical bed and nursing call system parts.
Communication Electronics
Connectors, exterior components, brackets, and light guides, and other communication and electronic components.

We are familiar with our clients’ stringent product standards (UL, V0, V1 fire ratings, RoHS, REACH environmental regulations), and can perform DFM assessments and mold flow analyses according to different project requirements to prevent shrinkage, warping and stress problems in advance.

Injection molding machines and 3D printing
Traditional injection molding machine
Suitable for high-volume, high-precision products. It is the mainstay of the company's mass production. It can be used with a variety of engineering plastics.
Miniature Injection Molding Machine
Designed specifically for tiny parts, it features extremely low plastic injection volume and high precision, and is commonly used in the medical and electronic fields.
3D printer
Creating 3D objects without molds is suitable for sample development and small-scale production. It's the main tool for prototyping and design verification.
Technical Authority
Strict process control and international quality verification have earned the long-term trust of global brands.

International Certification System
  • ISO 9001 Quality Management System
  • IATF 16949 Automotive Industry Quality System
  • UL Safety Certification System
Technical capabilities
The mold department possesses CNC, EDM, wire-cut, mirror polishing, and hot runner system repair capabilities, ensuring stable mass production and efficient maintenance.

Our mold and injection engineers are frequently invited to provide clients with product manufacturability consultations and material selection advice, helping them shorten development cycles and improve mass production stability. Internally, we have implemented a full-process traceability system, allowing for tracking from raw material batches and mold codes to production dates.
Trust Commitment
Strict inspection system
First Article Inspection (FAI) and mass production sampling inspection systems ensure the quality of every product.
Statistical process control
Implement SPC statistical process control and full-process quality assurance monitoring (IQC/IPQC/OQC) on the production line
Transparent management
Share process monitoring reports, mold maintenance records, and injection condition documents with customers.
Green manufacturing
Actively adopting energy-saving injection molding machines and recycled plastics technology, committed to green manufacturing.
For many years, we have become the most trusted OEM/ODM partner for our European and American clients through our stable quality and honest cooperation. In every step of the injection molding process, we uphold the philosophy that "quality equals trust."
Extended services
Mold Development and Maintenance
Self-design and manufacture of precision molds
Secondary processing
Spray painting, printing, ultrasonic welding, UV coating
Assembly and Testing
Injected parts can go directly to the assembly line for functional testing.
Packaging and Shipping
Customized packaging, barcode management, export security inspection

"From mold development to injection molding, from parts to complete machine assembly, we bring every product from design drawings to reality."
