Among them, the high-end laser bump signage was previously produced by the US DuPont 氦氖 laser, which is slow and costly.
Through many experiments, the ordinary laser version was used, and the electroless casting method was used for production, which was low in cost and fast in speed. The specific production process is as follows: Generally, we use glass and copper plates as substrates for making stencils.
For the process of making laser engraving, we used the 氦氖 laser of DuPont in the United States. After many experiments, we have our own set of production process, which is simple, low cost and easy to operate.

Duvet - the lightest quilt
The main fillings of duvets are goose down and duck down. Compared with the two, goose down quilt is better than duck down. But no matter what kind of duvet, its main quality index is down content. Generally speaking, the duvet with 50% down is a high-quality duvet.
Cotton quilt - the most common quilt.
As a traditional thermal insulation material, cotton is the most widely used quilt because of its fineness and natural curling, and a central cavity in the cross-section.
Wool (cashmere) quilt - the most intimate quilt.
Wool fibers have good crimp characteristics, so the thermal insulation of wool is unquestionable. And wool has good drape, so it has a good fit.
Fiber quilt - the cheapest quilt.
The fiber quilt can be divided into four-hole, seven-hole, nine-hole quilt, etc. Theoretically, the more fiber pores, the better the warmth, elasticity and air permeability. However, it is not necessary to choose a fiber quilt with a large number of holes. If the indoor temperature in winter is high, you can choose a four-hole quilt, because in fact, the warmth retention of these quilts is not much different.
