Plastic Injection Moulding
Cleaning Moulds – external surfaces
Plastic injection moulds are a major investment and need to be looked after. Surfaces can be cleaned with:
- Bio-Circle Mini-Compact-Maxi parts washers
- UNO S
These are VOC-free or VOC-reduced cleaners that are safe (non-flammable) and cost-effective. No need to use solvents or other toxic cleaners.
Highly polished moulds can be cleaned with FT 200 instead of alcohol – VOCs are reduced, leaves no residues, non-hazardous and easy to apply. This process was developed with and approved by LEGO.
Cleaning Moulds – internal cooling channels
The internal cooling channels typically become blocked with mineral deposits, reducing the cooling efficiency and productivity. Time is lost waiting for a mould to cool when it is not being cooled properly.
The RWR KST is a device specifically made for cleaning injection moulds. Power Cleaner DB (diluted) is pumped through the mould, dissolving the mineral build-up and removing it. Cooling channels are opened up completely and full cooling efficiency is restored.
Rust removal
Surface corrosion can be removed quickly and safely:
- E-NOX Clean
- Power Cleaner DB
- Bio-Rust
Power Cleaner DB can be used manually (spray on) in a variety of different equipment, eg hot water washer, ultra-sonic cleaner etc. E-NOX Clean is a gel that adheres to the surface.
NB: neutralise E-NOX Clean and Power Cleaner DB with water or UNO S after use.
Corrosion Protection
- Anti-Rust Wax – creates a thin, transparent and durable protective film, for transport or long-term storage. Does not run into the nest and does not need to be removed before production. Fast-drying, non-tacky – doesn’t attract dust.
- Anti-Rust Oil – liquid state, optimal for internal storage and maximum protection.
- OMNI – multi-purpose oil with excellent capillary action for lubrication, cleaning and protection.
