KW Variable Pump Injection Molding Machine KWV series high efficiency energy saving variable pump injection molding machine is equipped with high efficiency and high response proportional variable pump system. The power output is automatically matched according to the machine action. There's no waste of high pressure throttle and overflow power. It has sensitive dynamic following performance. In comparison with the traditional injection molding machine, energy saving reaches 20-40%. At the same time, it saves water and oil 20-40% that greatly increase profit. This machine applies high performance precise oil filter which keeps the oil pollution grate below NAS8 while in normal continuous working. Personal Purpose Hot Melt Adhesive And Equipment Hot melt adhesive is short for hot melt adhesive, it does not use any solvent in production and application, non-toxic, tasteless, does not pollute the environment, known as "green adhesive", especially suitable for use in continuous production line. The application of hot melt adhesive is very wide, according to its application can be divided into: fabric hot melt adhesive, packaging and bookbinding furniture edge with hot melt adhesive, hot melt adhesive with hot melt pressure sensitive adhesive, thermoplastic powder coating, multi-purpose solvent hot melt adhesive and so on Personal Purpose Hot Melt Adhesive And Equipment,Binding Agent,Yellow Adhesive Gun Strip,Hot Melt Stick Glue Strip Shenzhen Tongde New Materials Technology Co., Ltd. , https://www.tdhotmeltglue.com

Hot melt adhesive is a thermoplastic adhesive that is solid at room temperature but liquefied at higher temperatures. The molten liquid moistens the substrate, and when the adhesive layer cools and hardens, it forms gluing. The typical melting temperature is 65℃~180℃. Since it is 100% solid without any solvents, it can meet the most stringent air pollution control requirements and there is little risk of fire or explosion.
In addition, the hot melt adhesive has the following advantages for the user: â— curing speed is fast, reducing the amount of compression required for gluing, so the production speed can be improved, and the Equipment space is also saved. â— It can be applied to hydrophobic surfaces without the need for wet dissolving agents. Therefore, it has water resistance and excellent storage stability. â— Less waste because 100% solid parts are fully available, which can reduce transportation and storage costs. â— Wide range of substrates that can be followed and can be automated.
Hot melt adhesive has a wide range of uses, and can become an economical material if it can match the equipment and price. The packaging industry accounts for more than 50% of the hot melt adhesive application market, and these packaging materials include pleated cardboard boxes, corrugated cartons, laminated cans, tapes and other laminated coating materials. Non-woven textiles include sanitary napkins, diapers, clothing fitting, sewing and so on. Woven products include ready-to-wear, edging, tape, carpet backing. Office supplies include tape, documents, self-adhesive labels, envelopes, and folders. The parts portfolio includes soft drinks, electronics, book packaging, furniture, shoes, DIY handicrafts, as well as carpentry, plywood and more.
