What is injection molding?
Injection molding is a highly efficient manufacturing process that involves injecting heated, molten plastic into a metal mold to form parts with precise shapes and dimensions. Ideal for mass production, it is widely used in automotive, electronics, medical, and consumer industries. With extensive expertise in mold design and injection molding, we provide one-stop solutions from product development to volume production.
Plastic Injection Mold Materials
01
Steel Types
We select the most suitable steel types based on part design, production volume, and plastic material. Common choices include P20, H13, S136, and NAK80—each offering specific advantages in hardness, and corrosion resistance to guarantee long-lasting and efficient mold performance.
02
Materials
We recommend materials based on your product’s application, functional requirements, and working environment. Common options include ABS, PP, PC, PA, POM, and TPU, each offering unique characteristics in rigidity, elasticity, transparency, and wear resistance—ensuring optimal performance and cost-effectiveness.
03
Other Materials
Standard plastic materials may not always meet the specific requirements of custom injection-molded parts. In such cases, additives and reinforcing fibers can be introduced to enhance both visual and functional properties, providing added value and durability to your injection molded products.

Grinding Process for Sustainable Operations
At Yuhui Die Casting, we offer sustainable grinding processes that ensure both high production efficiency and environmental responsibility. Our approach includes:
Energy-efficient Equipment and Optimized Processes
We utilize energy-saving grinding equipment and optimize the entire process to reduce power consumption and material waste. This not only lowers production costs but also helps to minimize carbon footprints.
Waste Recycling and Reuse
Waste generated during grinding, such as abrasives, dust, and metal shavings, is effectively collected, sorted, and recycled. This reduces waste disposal and improves resource utilization.
Use of Eco-friendly Materials and Abrasives
We choose eco-friendly abrasives and materials that not only reduce environmental impact but also ensure our products comply with green standards and regulatory requirements.
Process Optimization and Automation
By integrating automated equipment with manual operations, we eliminate unnecessary production steps, optimize the process, and improve production efficiency while minimizing scrap rates.
Employee Training and Safety Management
We provide employees with training on environmental protection and safety to ensure that operations are safe and environmentally conscious, protecting both workers and the environment.
Through these practices, we maintain a sustainable and eco-friendly grinding process while delivering high-quality products and meeting global environmental standards.
