The structure of plastic mold for curbstone may vary due to the variety and performance of plastic, the shape and structure of plastic mold and the type of injection machine, but the basic structure is the same.
The material used in the production of plastic mold for curbstone is made of new high-quality polypropylene material. If the plastic mold is placed for a long time, the quality of the plastic mold will change, and the appearance is easy to turn yellow and gray. The plastic mold of curbstone can not be exposed to the sun and rain, and the mold itself will be mutated after long time exposure to the sun and rain.
When the customer shakes and flattens the plastic molds of the curbstone, the molds will break smoothly and vibrate and crack, and the deformation and damage of the products produced during the pouring process are easy to occur, and the concrete products are difficult to demould and easy to be covered with mucositis.
In the process of using the plastic mould of curbstone, it is the most important to use it within the "validity period", so as to avoid reducing the toughness and performance of the mould caused by too long time, which may cause unnecessary trouble for customers in production.
