Precautions in the use of plastic molds

1. The site for placing the prefabricated parts should be levelled.

2 before prefabrication mold must wipe release agent or release oil.

3. The mold with concrete needs to be laid flat.

4. It is forbidden to prefabricate components below 4 degrees.

5. The molds that are not used temporarily after demoulding need to be neatly placed after cleaning. Prevent deformation..

6. The hammering tool used when demoulding needs to be a wood hammer or a leather hammer.

7. When demoulding, it is necessary to use the demoulder or the bottom pad of the sack piece or straw bag or scrap tire to prevent damage to the prefabricated parts and molds.

8. The shaking platform should be cleaned regularly, kept flat, and cleaned up when the work is finished.

9. When prefabricating large components, if the mold is directly placed on the ground and the vibrator is used, the head of the vibrator needs to be covered with leather, otherwise the service life of the mold may be reduced.

10. It is easy to deform when prefabricating larger components or more reconstructed parts. It is recommended to use wood clips or use clips or use good iron frames.

11. When the temperature is high in summer, the prefabricated components need to be covered with sacks or straw bags or sunshade nets to prevent the sun from cracking the prefabricated parts, and water should be sprayed on time for maintenance.

12. When it is necessary to make prefabricated blocks with holes, the pipes used need to be drawn out in time. If the time is long, they cannot be drawn out.

13. When cement is stuck on the mold, it is forbidden to clean it with iron tools. It is recommended to soak with dilute hydrochloric acid or oxalic acid, and then clean it with soft cloth.
