Is there a difference between an extruder and the injection unit of an injection molding machine?

Simply put, the EXTRUSION process is required to create continuous linear, two-dimensional shapes. INJECTION MOLDING produces three-dimensional shapes that do not remain constant in a parallel line.

What are the different types of injection molding?

There are many different injection moulding process variations, including:

• Cube moulding.
• Die casting.
• Gas-assisted injection moulding.
• Liquid silicone rubber injection moulding.
• Metal injection moulding.
• Micro injection moulding.
• Reaction injection moulding.
• Thin-wall injection moulding.

What is minimum daylight in injection Moulding machine?

Minimum daylight = Minimum mould height + mould open stroke. With Hydraulic clamp machine, Maximum daylight = Minimum mould height + mould open stroke.

What is the price of injection Moulding machine?

Basic price is Rs. 22.1 lac +18\% GST….Questions & Answers on Plastic Injection Moulding Machine.

What is the difference between pultrusion and extrusion?

Extrusion pushes material through a die whereas pultrusion, as the name suggests, pulls the material through. Pultrusion utilizes composites that are reinforced with long strands of fiber, such as carbon, Kevlar or glass, and a resin. Extrusion is common for aluminum and thermoplastics.

What is extrusion Moulding machine?

From Wikipedia, the free encyclopedia. Extrusion is a manufacturing process used to make pipes, hoses, drinking straws, curtain tracks, rods, and fibre. The granules melt into a liquid which is forced through a die, forming a long ‘tube like’ shape.

What is the difference between two-color injection molding and common injection moulding?

Compared with common injection molding plastic products, two-color injection molding adopt higher melt temperature and injection pressure during injection. The main reason is that the molding flow in two-color injection molding is relatively long. The structure is relatively complex, and the flow resistance of injection melt is relatively large.

What is the difference between two Platen and three platen injection moulding machine?

So usually two platen injection molding machine need smaller space than 3 platen injection moulding machine, and better mold clamp precision. traditional three platen injection moulding machine use the toggle link system to generate the clamp force.

What is the function of valves in plastic molding?

During molding, after the molten material is plasticized in the barrel, two valves respectively control the sequence of molten material entering the nozzle and the proportion of discharged material. Then the molten material is injected into the mold cavity from the nozzle.
