Yuyao injection molding factory is better, preferably in the mold city.

Good injection molding refers to the business that customers provide raw materials and molds, and injection molding manufacturers manufacture injection products according to customers' requirements and charge processing fees.

Good injection molding is an industry with wide knowledge, strong technology and strong practicability. Plastic raw materials, toner, nozzle materials, molds, injection molding machines, peripheral equipment, fixtures, spraying, various auxiliary materials and packaging materials are needed in the injection molding process, which brings great workload and certain difficulty to the management of injection molding workshop. Compared with other industries or departments, the injection workshop has higher requirements for managers at all levels.

Injection molding production needs 24-hour continuous operation, and generally adopts double-sided three-shift or three-shift mode. There are many jobs in the workshop of injection molding workshop, and the division of labor is complex, so the skill requirements for people in different positions are also different. In order to make the production of injection molding workshop run smoothly, it is necessary to manage the personnel, materials, equipment and tools involved in each link and post, mainly including the operation and coordinated management of raw material room, waste room, batching room, production site, post-treatment area, tool room, semi-finished product area and office.

For good high-precision plastic parts, it is difficult to master the shrinkage rate. Generally, the following methods should be adopted to design the mold:

(1) The external diameter of plastic parts shall be smaller and the internal diameter shall be larger, so that there is room for correction after die test.

(2) Try to determine the form, size and molding conditions of the gating system.

(3) The plastic parts to be post-processed should be post-processed to determine the dimensional change (measurement must be made 24 hours after demoulding.

④ Correct the mold according to the actual shrinkage.

⑤ Re-test the mold, appropriately change the process conditions, and slightly correct the shrinkage value to meet the requirements of plastic parts.

Generally, the fluidity of thermoplastics can be analyzed from a series of indexes such as molecular weight, melt index, archimedean spiral flow length, apparent viscosity, flow ratio (flow length/wall thickness of plastic parts). Small molecular weight, wide molecular weight distribution, poor molecular structure regularity, high melt index, long screw flow length, low apparent viscosity and large flow ratio make the plastic of the same name have good fluidity. For the plastic with the same name, the specifications must be checked to determine whether its fluidity is suitable for injection molding.
