The recent inspections of relevant departments began to conduct random inspections on labor insurance products. From the overall situation, the quality of products is worrying. The results of random inspections showed that the quality index of supervision and spot checks last year was lower than expected. It is even more worrying that the amount of formaldehyde released from “shanzhai†safety plates exceeded the standard, which is directly related to human health. Given that both indices are low, it directly affects the physical health of the staff. To this end, the supervision department starts an emergency warning.
It is understood that the production process of safety shoes has high requirements for raw materials, auxiliary materials, chemical materials, machinery and equipment, etc., and the shoes worn at different workplaces to protect the feet and legs from foreseeable injuries . Safety shoes are high-tech and high value-added footwear products. Used to better maintain the safety of employees.
The unqualified items of plastic film are mainly tensile strength and elongation at break, which directly affect the performance of the product. gold
The main unsatisfactory items of the polystyrene sandwich panel are the bonding strength, surface density and peeling performance, which directly affect the performance of the product.
The main unqualified items for single-clip clothing are fiber content and color fastness. On the whole, the average pass rate is lower, and it is difficult to guarantee that employees may be injured by work injuries even if they have labor protection products protected.
In this reminder, pay attention to identify "cottage" fake and shoddy products, select the regular manufacturers, pay attention to see the labor insurance products business qualifications, or choose a well-known brand labor insurance supplies. Only in this way can we provide effective security protection and ensure the health of employees.

Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
Convex Aspheric elements are used to reduce aberrations, apheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
VIS coating option provides less than 1.5% reflection from 425 – 675nm. NIR coating option provides less than 1.5% reflection from 600 – 1050nm. Contact us for volume pricing of the custom aspheric lenses.
