China OEM Diy Plastic Injection Machine Quotes - Plastic drain grate cover – Mestech

The plastic drainage cover grid is made of plastic. The drainage cover is provided with array holes or slots in series. Plastic drain cover grilles are usually installed at the inlet and outlet of the indoor drainage system to filter and allow water to pass through.

Drain cover grilles normally are made of plastic, steel, cast iron and concrete, which is widely used in the indoor and outdoor drainage system of water pool and building facilities. For example: roof, toilet, kitchen, balcony, reservoir, swimming pool, sewer, city street, etc. The material of plastic grille is light and easy to be made by mould, and it is mostly used for indoor drainage system

The plastic drain cover grilles  are made of modified PVC, HDP, nylon and other corrosion-resistant materials. The plastic grid is made by injection molding, which is convenient for mass production and low cost. The weight of plastic grid is very light. With the application of plastic pipe in building water supply and drainage system, the plastic grid is more easily connected with drainage pipe through screw thread, with good sealing performance

Plastic grid injection molding process:

1. The holes and slots in the plastic cover grille are densely distributed, and bring difficulty to the plastic filling during injection molding. The location and size of the gate should be reasonably selected in the design of injection mold, in order fill as fast and fully as possible, improve the fusion line as much as possible, and reduce product deformation

2. The injection mold for the plastic drain cover is generally injection molded with large water port. To increase productivity.

3. Generally, because of the large size of mold, and large injection molding machine is generally used.
