Q:RT... What are the forming methods of plastic forming dies? Which expert answers, thank you very much...

3, plastic plastic mold: a plastic board sheet material forming a mold of some simple plastic products, its principle is to use vacuum or compressed air bloom forming method in the fixed die or punch on the plastic plate, sheet, and paste in the mold cavity on the necessary molding product deformation heating softening in the case of some aspects, mainly for daily necessities, toys, food packaging products production. Because the molding mould pressure is lower, the mould material is made of cast aluminium or non-metal material, the structure is simple.4, plastic wire drawing die: it is used to a mold for production of plastic wire, its principle is through the molten plastic extruder through a pore on the mold after cooling, drawing, drawing to form the final products rolling process. The material of the mould is mostly made of cold mould steel or nitrided steel, and the structure is simple.

Q:How to solve the main motor failure of aluminum-plastic packaging machine?

After the opportunity is switched on, the motor cannot start, but there is a buzzPossible causes:(1) the power supply is not all connected to single phase starting;(2) motor overload;

Q:What are the plastic forming dies?

For a combined plastic mold plastic pressure, extrusion, injection, blow molding and low foaming, which mainly comprises a die with variable cavity plastic mold die by the combination of substrate and die components and die combination clamping boards, die with variable core is composed of a convex mold substrate, punch, punch card, component combination cavity blocking assembly and side cutting plate. The coordinated change of die, punch, die and auxiliary forming system. Can be processed in different shapes, different sizes of series of plastic parts. Plastic processing industry and plastic molding machine matching, give plastic products with complete configuration and precise size tools. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so the plastic mold of the type and structure is various.With the rapid development of plastic industry and general and engineering plastics in the continuous improvement of the intensity and precision, the application of plastic products is also expanding, the proportion of plastic products is rapidly increasing. A rational design of plastic parts can often replace the more traditional metal pieces of plastic products is also the amount of. Rise.

Q:What are the features of carton packaging machines? Introduce concretely

And now complete the next part of adhesive tape paste, will be folded into cardboard boxes opened, the bottom of the box according to certain procedures, and sealed with tape, sent to the special equipment for the packing machine.

Q:Why should heat treatment be made after glass molding?

Therefore, in time after molding, the annealing furnace will be annealed in time to eliminate the stress.

Q:Types of blow molded products

Container consumption growth is presentod Xuanniu plastic container continues to expand, industrial consumption growth is mainly due to improvements in products by new technology, such as multi-layer parison extrusion, extrusion, biaxial non axisymmetric blow molding etc.. The application and performance requirements of some blow molded products are listed in table 2.

Q:Would you like to ask what is the difference between a cold stamping foil and a plain foil wrapper?

The specific technological process of producing aluminum foil is determined by the kinds of alloy, finished product specifications, product quality requirements, yield, specifications of production equipment and production capacity

Q:What are the factors affecting the packaging quality of bag molding, filling, sealing and packaging?

What are the factors affecting the packaging quality of bag molding, filling, sealing and packaging?First, material impactThe general composite film type food packaging bag has a certain heat sealing performance, mainly after the product is loaded into the customized food packaging bag and can be sealed through a sealing machine.

Q:The film pulling mechanism of the vertical bag forming machine is a little inclined at the left of the synchronous toothed belt pulley

The bottom belt is inserted into the guide bar. There will be no previous situation. Powder, because the surface is vulcanized, nitrile rubber is not wear-resistant. The effect of silicone on subsequent processing is much better.

Q:What are the characteristics of plastic thermoforming?

Mold manufacturing convenient. Hot forming mould has the advantages of simple structure, low cost of material, easy manufacturing and processing, high requirements for materials and manufacturing, and easy to modify, can be made of Gun C Muki S and other materials, the cost is only 1/10 of the injection mold, and the product design changing quickly, suitable for small batch production of parts.5.The production efficiency is high. When using multimode production, the output can reach hundreds of pieces per minute,.6.The utilization rate of waste material is high
