Which is Better? Natural Rubber or Synthetic Rubber?
Categories: Rubber Molding
Natural and synthetic rubber each offer distinct advantages in industrial manufacturing. Natural rubber, sourced from rubber trees, provides high resiliency and tensile strength but has limitations with UV and heat exposure. Synthetic rubber, engineered in chemical plants, offers consistent quality, adaptability, and better resistance to environmental factors like oils and extreme temperatures.

Injection Rubber Molding
Injection rubber molding is a popular manufacturing method for creating custom and standard rubber parts, particularly for high-volume production and intricate designs. The process involves feeding uncured rubber into a machine, liquidizing it, injecting it into a mold cavity, and curing it under high pressure and temperature.

Fixed vs. Closed Dimensions for Rubber Molds
When manufacturing rubber parts, understanding fixed dimensions (machined cavity spaces) and closed dimensions (where mold halves meet) is crucial for proper mold design. Engineers must consider various factors including shrinkage, tolerances, and flash formation to create parts that meet functional requirements while following industry standard tolerance classifications.
