The inspection standards for the quality of plastic energy chains mainly focus on the following aspects:
Identify the raw materials. judging from the smoothness and color of the appearance, more professionally, you can expose the finished chain links to sunlight. lf the reflection is uniform and there is no astigmatism, it proves that the raw materials are of good quality. When placed flat on the desktop, for a good plastic Energy Chain, the sliding strips on both sides will be slightly raised, while for a poor one, the two ends will be raised relatively high.
Impact strength, notched impact strength and Rockwell hardness of the energy chains.
The flexibility during the reciprocating movement, the bending and roling performance of the energychain. For a good plastic energy chain, it can roll nimbly and conveniently without significant jamming. However, for a poor one, the jamming and unsmooth situations are quite obvious.
The flame retardant performance mainly depends on flame retardancy and glow wire.
The factors affecting the performance of energy chains mainly include the following aspects:
Physical properties are achieved by checking its density;
Rheological properties refer to the mass flow rate and mold shrinkage rate, which are the conditions of energy chains under temperature changes;
Thermal properties include the heat -distortion temperature and Vicat softening temperature of energy chains;
Mechanical strength testing items include tensile strength, elongation at break, bending strength, and unnotched impact.
ZHEF has been in business for more than ten years, we take the medium-to-high-end route in terms of quality. The enterprises we serve are spread all over the country. Quality and cost performance are the foundation for our survival.
