Use of silicone spray in plastic injection molding machines
1. As a mold release agent
- Facilitates easy removal of plastic parts from the mold
- Reduces sticking and surface damage
- Especially helpful in molds with complex geometries
2. For machine maintenance
- Moving mechanisms (rails, slides, cover systems)
- Creates a protective film, reducing friction
- Provides surface protection against rust and moisture formation
3. Rubber and sealing elements
- Preserves the flexibility of O-rings and gaskets
- Delays drying and cracking
Advantages
- Easy part ejection
- Smooth and slippery film on the surface
- Corrosion and moisture protection
- Low-cost maintenance solution
Points to consider
- Excessive use can cause surface defects (staining, surface imperfections)
- Reduces adhesion on parts to be painted or coated
- Can accumulate in the mold → creates a need for cleaning
- The appropriate type of “mold release silicone” must be selected for the production process
- Must be considered in conjunction with injection parameters
Where not to use
- On surfaces of parts to be painted, coated, or glued
- On sensitive optical or electronic surfaces
- Continuously and heavily on all unnecessary mold surfaces
