Introduction: Injection molding machines, also known as injection or injection molding machines. The main function is to heat the plastic and allow the molten plastic to be ejected and filled with the mold in a high pressure environment. Injection molding machines are currently divided into vertical, horizontal, all-electric.
What problems should be noticed when relocating the injection molding machine? The professional staff of the large-scale equipment relocation office in Beijing proposed the following suggestions:
1. Remove all accessories outside the machine before relocation. In addition, if it is a new machine, plastic packaging outside the machine is kept so as not to damage the appearance of the machine during the relocation process.
2. Before the relocation, all the hydraulic oil needs to be pumped out to prevent the liquid in the tank from flowing back.
3, if you need to hoist, you must find a professional lifting company to carry out operations, and pay attention to protect the rod.
4, in order to protect the injection molding machine from damage, in the relocation process is best to use air cushion relocation, this can reduce the risk of machine damage.
5. Perform appropriate reinforcement work on the moving parts of the injection molding machine to prevent them from slipping and damaging the components during the relocation process.
6. If demolition and relocation are adopted, the disassembled wires, tubing, and conveying lines shall be marked accordingly to avoid mistakes during the later installation.
7, for disassembled parts, should be cleaned in time, and do a good job of anti-rust work.

Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
