The best coating for injection moulding
TECHNO MIDA Srl offers multiple proposals that represent both tradition and innovation in the field of wear-resistant, anti-corrosive and anti-stick coatings: flash hard chrome, hard chrome plating, DLC (Diamond Like Carbon), “anti-sticking” silicon oxide.
TECHNO MIDA is an ISO 9001 and 14001 Coating Centre specializing in offering excellence in anti-friction and anti-oxidation coatings for mechanical parts and moulds.
During the moulding process, polymers (thermoplastic elastomers), also known as thermoplastic rubbers, tend sticking to the parts; these residues jeopardize the moulding process by altering the moulded particulars geometrically and dimensionally.
The proposed anti-sticking Silicon Oxide surface coating fulfils the following expectations:
Facilitating the release of the moulded material by increasing the plastic flow,
Preventing the moulded product from being deformed or damaged superficially,
Preventing the mould cavity from being partially occupied by the adhered material.
On TPE, TPE-E Arnitel/Marfran and TPE-V Taroprene polymers, the coating grants the following benefits:
1. Easier cleaning
2. Less production waste
3. Higher quality of finished products
For elastomer polymer injection moulding, the anti-sticking Silicon Oxide coating stands as an improvement over traditional “thin film” coatings: CrN (PVD), WC/C (PVD), and DLC.
Advantages the coating offers:
Hydrophobic and anti-sticking coating
Reduced wettability and surface sticking
Coating suitable for food use REG EU 1935/2004 & FDA food contact.
