Types Of Plastic Industry Mould Maintenance

Types of Plastic Industry Mould maintenance

daily preventive maintenance

These are maintenance performed daily, weekly, monthly, or yearly. This ensures smooth operation. This includes; mold inspection, cleaning, lubrication of moving parts, and other routine maintenance. Less routine maintenance may include more intensive cleaning of the injector unit.

Non-routine/diagnostic maintenance

This is not an ideal method. This means that a failure occurred before maintenance was performed. This usually happens after a failure. Engineers then conduct maintenance checks. This is to see how to fix the problem and then diagnose it.

Some tips for maintaining mold

It's important to make sure the product is well designed first. Poor design can lead to problems such as difficult ejection and poor mold filling. Make sure to use the correct draft angle, the correct ejector pin position, and the correct gate. Failures in other parts of the injection molding machine may end up in the mold. At the same time, the mold can be well operated and maintained. If other processes in the injection molding machine are not running well. The resulting problems may be transferred to the mold. For example, if the injection pressure is too high, it may put unnecessary stress on the mold. Or if the melt is not well mixed and melted and contains particles that can damage the mold surface. It is important that other parts are also well operated and maintained. This is to ensure that these factors are considered first.

A maintenance plan that is followed

There should be a written maintenance plan. This includes procedures for maintenance work.

The process of confirming maintenance work performed and when the next maintenance is due

Each mold should be accompanied by an operating and maintenance instruction manual and checklist. This guides the operator and reduces the chance of human error.

A feedback system that allows errors to be detected before they occur

Proper training and ongoing training for operators

Periodically inspect cavities, gates, and runners for wear, blockage, and damage

lubrication or surface

Regularly clean and remove debris from the cavity and all components

Make sure the cleaner is non-toxic and use recommended solvents and cleaners

Use anti-corrosion or rust inhibitors and coatings

Avoid moisture problems by properly flushing and draining water lines

Check the plate is well aligned

Make sure the ejection system is unobstructed and functioning properly

Clean and lubricate thimbles and parts

Check and replace all parts that need to be replaced, such as pins, screws, bolts, and bushings

There is a routine for replacing parts after a certain level of use. Even if there is no detectable damage. This promotes a maintenance culture that minimizes the chance of mold damage

Follow mold manufacturer's operating and maintenance guidelines, if provided. The mold maker may have some advice on how to best operate and maintain the mold. Take these suggestions seriously.

There is a system to keep track of the number of cycles the mold runs. As many molds are rated according to the number of cycles. Depending on your size and capabilities, this can be a digital or analog system for tracking. The bike lane can then be used as a maintenance indicator.

Make sure other parts and processes work well.

Check that the cooling lines are well sealed and free of leaks. This can lead to corrosion or cooling inefficiencies

Have a dedicated maintenance budget
