Three methods of how to make blowing moulds and blowing mould maintenance.

Good blowing mould structure design is a prerequisite for qualified blowing mould manufacturing. Various aspects of blowing mould structure and product structure (including:blowing mould flow analysis, stripping slope, microcosm of product surface, design (gating system, exhaust system design, cooling system design, etc.). These  blowing moulds are the most important and the most prone problems It is repeated testing during the  blowing mould structure design process.

We need to choose the right steel for the  blowing mould frame and  blowing mould cavity. In addition, high-hardness steel must be used as the  blowing mould frame, and then select the appropriate  blowing mould standard parts. A good plastic filling system requires the assistance of a special hot runner system to ensure the best effect of the cooling system.

 blowing mould maintenance is mainly divided into three points:

1. Daily maintenance: Various moving parts such as thimble, line position, guide post, guide bushing, cleaning of the  blowing mould surface, and water transportation, which are maintained every day during  blowing mould production.
2. Regular maintenance: Regular maintenance includes the cleaning of the exhaust slot in addition to daily maintenance, trapped gas burns to the black level plus exhaust, damage, wear parts correction, etc.
3. Appearance and maintenance: Paint the outside of the  blowing mould base to avoid rust. When lowering the  blowing mould, the fixed  blowing mould moving  blowing mould should be coated with anti-rust oil. When the  blowing mould is stored, it should be closed tightly to prevent dust from entering the cavity.
