| Feature | Transfer Molding | Compression Molding |
|---|---|---|
| Process | Material is preheated, then forced into a closed mold cavity through a runner system | Material is placed directly in an open mold cavity, then compressed |
| Tooling Complexity | More complex tooling with additional runner and pot system | Simpler tooling with no runners |
| Part Complexity | Suitable for complex shapes and inserts | Best for simpler, flatter parts |
| Cycle Time | Typically faster due to preheating and flow | Generally slower because heating occurs in the mold |
| Material Waste | More waste due to sprues and runners | Less waste, since all material is used in the part |
| Cost | Higher tooling cost | Lower tooling cost |
| Consistency | Better dimensional accuracy and consistency | May have more variation in thick or uneven parts |
| Use Cases | Electronic components, encapsulation, precision parts | Gaskets, seals, large simple rubber parts |
