Five advantages and three disadvantages of injection molding
Five advantages of injection molding
1. High tolerances are repeatable.
2. A wide range of materials can be used.
3. Low labor costs.
4. Minimal scrap loss.
5. No need to continue to improve the parts after molding.
Three disadvantages of injection molding
1. Expensive equipment investment.
2. Running costs can be high.
3. Parts must be designed to specific molding requirements.
Injection molding is a relatively new way to manufacture parts. It is a fast process used to produce large quantities of identical items from high-precision engineering parts to disposable consumer goods.
Injection molding is often used for mass production. It produces small products such as bottle caps, sink plugs, children's plastic toys, plastic containers, model kits, disposable razors and camera parts.
The process can even mold large items such as ship hulls and automobile plastic shells.
