What are the advantages of injection molding? - Custom Rotomolding - Custom Plastic Molding

 

Our advanced rotomolding technology allows us to create custom solutions that exceed expectations, providing durable and innovative plastic Products to meet your most unique needs.

 

Injection molding involves first adding plastic to a mold, then continuously rotating and heating the mold along two perpendicular axes. Under the influence of gravity and heat energy, the plastic inside the mold gradually and evenly coats, melts, and adheres to the entire surface of the mold cavity, forming the desired shape, which is then cooled and solidified.

 

Compared to traditional blow molding and injection molding processes, rotomolding offers the following advantages:

 

1. Cost advantage: The rotomolding process only requires the strength of the machine frame to be sufficient to support the weight of the material, mold, and the frame itself, and to prevent material leakage with a closed mold force.  Furthermore, during the entire molding process, the material is almost unaffected by any external forces except for natural gravity, thus offering the advantages of convenient machine and mold manufacturing, short cycle time, and low cost.

 

2. Quality advantage:  Because no internal stress is generated during the entire production process, rotomolding products have more stable quality and structure.

 

3. Flexibility and versatility advantage: The convenient and inexpensive manufacturing of rotomolding molds makes it particularly suitable for multi-variety, small-batch production in new product development.

 

4. Personalized design advantage: Products made with the rotomolding process can easily change colors and can be made hollow (seamless and weldless). Surface treatments can achieve patterns, wood, stone, and metal effects, meeting the personalized needs of modern consumers.

 

Products produced using this process include: fuel tanks, water tanks, machine housings, fenders, etc.  The main replacements are metal parts and fiberglass products.

 

Injection molding is a process developed based on micro-manufacturing technologies such as LIGA, and there are many other methods as well.
