Disadvantages of injection molding
- Injection molds cost 15 to 20 times the cost of a rotational molding tooling due to the high pressures required to manufacture injection molded products.
- Parts tend to be weaker and do not perform as well as rotomolded parts especially in outdoor conditions.
- Part size is limited due to machine capacity requirements. It can be very expensive to tool up and manufacture a large injection molded product.
- There are certain design limitations.
- Short runs are not achievable without paying high setup costs.
Advantages of injection molding
- Good tolerances on small parts allow consistent repeatability.
- Cycle time are short.
- Parts are relatively inexpensive.
