What is the quality of blow-molded pallets produced by Zibo Linjie Company?

How about the quality of blow-molded pallets? We should understand and control from four aspects:

First, the plastic pallet raw materials

1, raw materials are not suitable for pallet production.

Manufacturers of plastic pallets find that bad raw materials have a great influence on the performance of pallets. For example, the pollution of components with large molecular weight distribution, rigid molecular chains or other plastics with uneven structure, the pollution of bad additives and dust are also the reasons for embrittlement.

2. Too many returned materials

If the plastic is recycled too many times or the content of recycled materials is too high, or the heating time in the barrel is too long, the parts will become brittle.

3. Bad additives

The raw materials are mixed with other impurities, or are doped with inappropriate or excessive solvents or other additives.

Second, the plastic tray technology

1. In the production process, try not to add metal and other accessories to the tray. If necessary, it can be dealt with later.

2. The core should have a suitable demoulding slope. This can facilitate demoulding and take out the tray faster.

3. Plastic pallet manufacturers suggest that the temperature of the mold is too high or too low, which is not conducive to the production of pallets. Too low film temperature is easy to make the tray brittle. The temperature of the barrel and nozzle should not be too low.

4. Reduce the back pressure and rotating speed of the screw preform, make the material of the feed inlet loose, and reduce the plastic degradation caused by overheating.

Third, the plastic pallet product design

1, plastic pallet manufacturers suggest that if the product wall thickness is too thin and the overall weight is too light, the overall impact resistance of the pallet is not strong.

2. If there are too many hollow structures in the tray, the plastic tray will become brittle.

Four, plastic pallet equipment

1. If the ejection device is unstable, it will tilt, and the ejected product area will become smaller or unevenly distributed.

2. The plastic pallet factory suggested that the plastic raw materials were heated and stirred in the barrel for too long, and the plastic was easy to age, which eventually made the products fragile.

3. There are dead corners or obstacles in the barrel during production, which is easy to promote material degradation.
