What is MTC in injection moulding?

Pumps for Mould Temperature Control (MTC) are widely used in Plastic Moulding, Tyre Moulding, Rubber Moulding industries etc. The process of injection moulding thermoplastics, hot melt is periodically injected into a cold mould.

What is injection Mould cycle process?

The whole injection moulding process usual lasts from 2 seconds to 2 minutes. There are four stages in the cycle. These stages are the clamping, injection, cooling and ejection stages.

What is soak time in injection moulding?

times the injection capacity and soak for 5 minutes. When routinely purging with Purgex™, use approximately 1 to 1-1/2 times the injection capacity and soak for 3-5 minutes.

What is preventive maintenance of mould?

Preventative mould maintenance refers to the periodically scheduled maintenance tasks done on the injection moulds, such as inspections, assessments, cleaning, repairs, and replacements of worn-out components to keep the injection mould in tip-top condition to prevent avoidable part quality lapses and production …

What is mould maintenance?

Mold maintenance, or tool maintenance, refers to the cleaning and repairs that are needed to keep an injection mold in the best working order. Maintenance is performed routinely over the life of the mold (preventative maintenance or PM), and also when any problems arise.

What is mold temperature range?

A common range typically lies between 300 and 800°F (149 and 426°C). The temperature maintained in the mold is equally as important as the temperature profile in the barrel.

What is the maximum temperature and pressure allowed to the injection molding process?

8. What is the maximum temperature allowed to be given to the injection molding process? Explanation: The maximum allowable temperature that can be given to the system is 300°C, in this particular method of molding.

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.

How do you reduce cycle time in injection moulding?

Six Ways To Reduce Cycle Time In Injection Molding

1. Keep wall thicknesses to the minimum required for your part or product to function effectively.
2. Ensure that your machine is fine-tuned and up to the tasks of proper injection pressure and speed.
3. Invest in people — not just in machinery.
4. Consider your material selection.

What is meld line?

A meld line occurs when two flow fronts blend together at an oblique angle. The orientation of the plastic molecules is therefore more uniform than the orientation after a weld line has formed. The following diagram shows the length of a part where a meld line forms. The red arrows show the direction of plastic flow.

What is shrinkage in moulding?

Shrinkage is the contraction of a plastic moulded component as it begins to cool after the injection process. All plastics shrink as they cool from viscous liquids to solids, and every type of plastic shrinks in a slightly different way.
