Understanding and Preventing Cracks in Molded Parts
Cracks in molded parts are one of the most common and concerning defects that can compromise part integrity. They can lead to failures in critical applications, resulting in costly recalls, repairs, and potential safety hazards. Understanding the types, causes, detection methods, and prevention strategies for cracks is crucial for anyone ...

01
Material Loading
Raw material, often in the form of pre-measured pellets or sheets, is carefully loaded into an open mold cavity.
02
Mold Closure and Heating
The mold is securely closed, and it's heated to a temperature that softens the material, making it malleable and ready for molding.
03
Compression and Curing
The closed mold is subjected to high pressure, causing the material to flow and fill the mold cavities. Simultaneously, the material undergoes curing or vulcanization, a chemical process that transforms it into a solid and durable product.
04
Cooling
After the material has taken the shape of the mold and undergone curing, the mold is cooled. Cooling solidifies the material, ensuring it maintains the desired shape and properties.
05
Cycling
The process is highly automated and can be repeated in a continuous cycle, producing a large volume of identical parts with high precision and efficiency.
Advantages of Compression Molding
From intricate designs to high-volume production, compression olding stands out with its precision, efficiency, and adaptability.
- Cost-effective for large production runs due to its high prodcution output and reduced material waste.
- Ensures consistent part quality and minimal variation between parts in large batches.
- Well-suited for high-volume prodcution, contributing to faster lead times and efficient manufacturing processes.
- Minimized material waste, contributing to a more sustainable and environmentally friendly manufacturing process.
Compression Molding Application
Compression molding produce a wide range of rubber and plastic molding parts across varios industries. Here are some common parts.
- Rubber seals and gaskets
- Plastic insulators for electrical components
- Rubber industrial bushings
- Consumer goods handles
- Plastic enclosures for electronic devices
- Oil seal

FAQs of Compression Molding
What are the factores affecting compression molding?
Important factors to be considered before the compression molding process are the following:
- Amount of plastic material
- Heating time
- Melting temperature of plastic material
- The pressure required to squeeze the material into the mold cavity
- Cooling time
Is compression molding good for environment?
Compression moulding can help reduce the environmental impact of plastic production and disposal by minimizing waste and energy consumption and using recycle materials.
What is the cycle time of compression molding?
Compression molding require slower cycle time than injection molding, the time needed to start and repeat the sequence of operations is between 1-6 mins for compression molding.
Is compression molding cheaper than injection molding?
Injection molding is better suited to high-volume production, whereas compression molding is better suited to pliable and flexible materials. Generally, the upfront costs for compression molding are cheaper.
