How to improve the productivity of injection molding?
Improve injection molding facility productivity
- Optimum run size first.
- Optimization of molding activities.
- Monitoring of production rates.
- Scrap Reduction.
- Mold preventative maintenance.
- Shorter Setup times.
Which process is suitable for making injection molding tools?
The electrical discharge machining (EDM) or spark erosion process has become widely used in mould making. As well as allowing the formation of shapes that are difficult to machine, the process allows pre-hardened moulds to be shaped so that no heat treatment is required.
What is Quick Change injection Moulding techniques?
Quick change injection moulding techniques – A technique where a mould may be adapted or changed in order for a different shape mould to be created.
Why is injection Moulding good for mass production?
The use of injection molds for mass production is great for achieving higher efficiency. Once designed for a specific purpose based on a customers choice, molding process doesn’t take long. This makes it a lot more effective in mass production and also a lot more efficient in output rate.
What is dwell time in injection Moulding?
In injection molding, the liquid polymer mass is forced into the mold and held under pressure at a particular temperature (the dwell or mold temperature) for a certain period (the dwell or molding time) before cooling.
How do you increase flow mark in injection Moulding?
HOW TO IMPROVE FLOW MARK IN INJECTION MOLDING
- Cold Sludge Well.
- Use Gates and Runners that are wide enough.
- Reduce distance from the hot nozzle to mold.
- Increase Back Pressure.
- Increase Temperature.
- Increase injection speed.
- Fillet Edges and Corners.
- Gate Location.
How do you control flow marks in injection Moulding?
How to Prevent Flow Lines
- Increase the injection speed, pressure, or material temperature: Slow-moving molten plastic is more likely to cool quickly and cause flow lines.
- Round the corners of the mold where wall thickness increases: This helps keep flow rate consistent to the thicker sections and prevents flow lines.
