Compression Molding Service Surface Finishing

Proper surface finishing will improve the molded parts' quality. Zhongde offers a wide range of surface treatment options. These efficient surface finishes improve the part's functions and aesthetic appeal.
surface finish Glossy

Glossy

A-grade finish is smooth and highly reflective, giving the product a shiny appearance. It’s often used for products where aesthetics are important.

Compression Moulding Fundamentals

  1. The material is placed into the mold.
  2. The product is heated until somewhat soft and pliable.
  3. A hydraulic tool presses and closes the molds together.
  4. Once the material is hardened, open the mold and the ejected pin will eject the custom parts out.

Compression molding is widely used across various industries for producing parts with high precision and quality. Common applications include: Automotive Components: Gaskets, seals, bushings, and various interior components. Electrical Components: Insulators, connectors, and housings. Aerospace Parts: Seals, gaskets, and interior components. Medical Devices: Seals, gaskets, and components for medical equipment. Consumer Goods: Handles, grips, and various molded products. Industrial Components: Gaskets, seals, and custom molded parts. The versatility of compression molding makes it suitable for a wide range of applications across different industries.

There are five advantages of compression molding services.

  1. Less mold structure with competitive tooling price.
  2. Evenly heated mold cavity with good dimensional stability.
  3. Little material waste suitable to work with expensive material.
  4. Available for forming large flat products.
  5. More than hundreds of colors to choose from.

Both injection molding and compression molding offer unique advantages, and the choice between them depends on specific project requirements. While some benefits may overlap, there are distinctions that make each method suitable for different scenarios:
  1. Low Initial Cost: Compression molding often has a lower initial cost, making it more cost-effective for smaller production runs. Injection molding can be cost-effective for large-scale production due to its high-speed, high-volume capabilities.
  2. Suitability for Large Parts: Both methods can handle large parts, but compression molding may have an edge in certain cases, especially for large, complex shapes.
  3. Enhanced Strength: Compression molding can produce parts with enhanced strength, particularly when dealing with composite materials. Injection molding provides high precision and can achieve good structural integrity.
Ultimately, the selection between injection and compression molding hinges on the project's specific needs, material requirements, production volume, and desired outcomes.
The cycle time for compression molding can vary widely depending on factors such as the material being used, the size and complexity of the part, and the specific process conditions. Generally, cycle times can range from a few minutes to several minutes. Smaller and less complex parts may have shorter cycle times, while larger or more intricate parts may require longer cycle times for proper curing and cooling. It's essential to optimize cycle times for efficiency while ensuring that the material is adequately cured and the part retains the desired properties. Manufacturers may conduct testing and experimentation to determine the optimal cycle time for their specific compression molding process.
