This 50-question guide provides practical, technical, and commercial answers for anyone planning to enter or expand in the blow moulding machine industry. All pricing inquiries should be directed to Dharmanandan Techno Project Pvt. Ltd., a trusted name in blow moulding machine solutions.
General Understanding & Machine Basics
What is a blow moulding machine and how does it work?
A blow moulding machine is used to manufacture hollow plastic components like bottles, jars, tanks, and containers. The process involves melting plastic, forming a parison (tube-like structure), and inflating it inside a mold to get the desired shape. Machines are typically categorized as automatic or semi-automatic based on the level of human involvement.What is the difference between automatic and semi-automatic blow moulding machines?
An automatic blow moulding machine handles the full production cycle (feeding, heating, blowing, and ejection) without manual intervention, offering higher production speed and consistency. A semi-automatic blow moulding machine, on the other hand, requires manual loading/unloading and may need more manpower, making it suitable for low to medium production.
What types of plastic materials can be used in blow moulding machines?
Common plastics used in blow moulding machines include HDPE, LDPE, PET, PP, and PVC. The choice depends on the product being manufactured (e.g., food-grade PET for beverages, HDPE for detergent bottles).
What are the main components of a blow moulding machine?
A blow moulding machine consists of:
- Extruder or injection unit
- Parison or preform former
- Blow pin or stretch rod
- Clamping system
- Mould cavity and mold cooling
- Control panel (PLC or manual)
Which industries commonly use blow moulding machines?
Industries using blow moulding machines include:
- Packaged drinking water and soft drinks
