5 Steps to Maintain Your PVC Extrusion Mould for Longer Life

2025-09-29

A PVC extrusion mould is an essential tool for creating profiles, pipes, and seals. Whether you’re a small business owner or a DIY enthusiast, you want your mould to last as long as possible. Good maintenance doesn’t have to be difficult. Follow these 5 simple steps to keep your mould in top condition.


1. Clean After Every Use

Material residue can cause uneven surfaces in the next batch. Wipe down the mould after use and remove any leftover PVC or plastic.


2. Control Temperature Carefully

Overheating can damage the mould surface. Always follow the recommended temperature range for PVC extrusion moulds to avoid stress or cracks.


3. Use Anti-Corrosion Treatment

PVC materials may produce chemicals that slowly damage the mould. Applying anti-rust or anti-corrosion coatings will extend the mould’s lifespan.


4. Store in a Dry Place

Moisture can lead to rust. Keep your moulds in a dry, ventilated area, and cover them if not used for a long time.


5. Schedule Regular Inspections

Don’t wait until the mould breaks. Inspect polishing, tolerance, and alignment regularly. If you notice wear, fix it early—it’s cheaper than replacing the mould.

Maintaining your PVC extrusion mould doesn’t take much effort, but it makes a huge difference in product quality and cost savings. Follow these five steps, and your mould can serve you well for years. It’s like giving your tools the respect they deserve.
