At present, the commonly used polishing methods are the following

1.1 mechanical polishing: Mechanical polishing is a polishing method to obtain a smooth surface by cutting and plastic deformation of the surface of the material to remove the polished convex part. Generally, oilstone strips, wool wheels, sandpaper, etc. are used, mainly by manual operation. For special parts such as the surface of the rotary body, auxiliary tools such as turntables can be used, and the method of ultra-fine polishing can be used for high surface quality requirements. Super-finishing polishing is the use of special grinding tools, containing abrasive polishing fluid, tightly pressed on the workpiece is processed surface, for high-speed rotation. 1.2 chemical polishing Chemical polishing is to make the surface of the material in the chemical medium micro convex part of the concave part of the preferential dissolution, so as to get a smooth surface. The main advantage of this method is that it does not require complex equipment, can polish workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency.

Plastic Mold Manufacturing Process

Plastic Mold Manufacturing Process

"Fast": It requires the preparation of the shortest time-consuming process documents in the shortest time. The following four points should be paid attention to in the work: 1. Technologists should be able to be familiar with the machine tool equipment and technical level of the unit. It is best to operate each machine tool and have a good understanding of processing to meet the requirements of complexity and particularity of mold parts. They can quickly determine the best processing flow and improve the speed by getting a drawing. 2. Determine the reasonable minimum machining allowance. Between the upper and lower processes and the coarse and fine processes, the necessary machining allowance is set aside to reduce the processing time of each process. 3. As the mold parts are mostly single pieces, small batches and process cards, they cannot be as careful and detailed as batch products, but they should strive to understand at a glance without omission. The key processes should be clearly explained and the processing precautions should be clearly written, and the operation guidance should be written to reduce the adaptation time of operators and reduce processing errors.

Plastic mold injection process

Plastic mold injection process

1) Injection process action selection: General injection molding machine can be manually operated, can also be semi-automatic and fully automatic operation. Manual operation is in a production cycle, each action is realized by the operator to switch the operation button switch. Generally, it is only selected when the test machine is adjusted. When semi-automatic operation, the machine can automatically complete the action of a work cycle, but after each production cycle is completed, the operator must open the safety door, remove the workpiece, and then close the safety door, the machine can continue the next cycle of production.
