Their working principle involves heating a thermoplastic material, shaping it into a parison, and then using compressed air to blow it into the desired mold shape.
B. Benefits of Manual Blow Moulding Machines
Manual blow moulding machines offer several advantages over other types of blow moulding machines. These include:
1. Cost-effectiveness: Manual machines are more affordable compared to fully automated counterparts, making them an attractive choice for small-scale operations.
2. Versatility: These machines can produce a wide range of shapes and sizes, making them suitable for various applications.
3. Customization: Manual machines allow for easy customization of products, enabling manufacturers to cater to specific customer requirements.
4. Simplicity of operation: Manual blow moulding machines are easy to operate and require minimal training, making them accessible to a broader range of operators.
II. Techniques in Manual Blow Moulding
A. Extrusion Blow Moulding
Extrusion blow moulding is a common technique used in manual blow moulding machines. The process involves extruding a tube of molten plastic, also known as a parison, and then blowing it into the desired shape using compressed air. This technique is perfect for producing hollow containers such as bottles, jars, and jugs.
B. Injection Blow Moulding
Injection blow moulding is another technique employed in manual blow moulding machines. In this process, a preform is injection-moulded, transferred to a blow mould, and blown into the desired shape. This technique is commonly used to manufacture small-sized containers and medical supplies that require precise dimensions.
III. Applications of Manual Blow Moulding Machines
