PS carrier tape is a kind of ribbon product applied in the field of electronic packaging. Holes for holding electronic components and positioning holes for index positioning are equally distributed in its specific thickness and length direction. How many processing methods are there for PS carrier belt?

1、 Thermoforming is generally divided into four working modes: conventional forming, rotary station forming, continuous hot die and continuous roll feeding forming. The thick plate is heated by convection heating furnace, and the thin plate is heated by radiation furnace to soften it to the forming temperature. The forming process has high requirements for the quality of sheet metal, which must be paid attention to during extrusion molding.

2、Injection molding, PS carrier belt can be processed into a kind of material with good dimensional stability. Because the production cycle of plastics is relatively short and the cost is low, it is very suitable for a variety of injection molding products. The cylinder temperature is generally between 390 ~ 500F. In order to shorten the production cycle and improve the product quality, the injection system with ultra fast injection speed and recovery speed has been put into use. There are many kinds of molds used in the factory, including the design of hot runner system and various gate forms.

3. foam forming should use different foaming agents, such as pentane, nitrogen, chemical foaming agent (CBA) and Freon. According to the use, the ingredients of additives can be more than 10, or they can not be added.

4、 Extrusion molding, most PS carrier belts are used, most of which are used to produce leather. The plate itself can be sold or hot formed by the manufacturer. Various profile products from building materials to corrugated plates can be used for extrusion molding of PS transparent sheet and PS impact resistant sheet. Two stage extrusion equipment is generally used for extrusion and molding of non foaming products, and its temperature range is 380 ° f (feed section) to 430-460 ° f (extrusion section). A new generatio
