The composition of the pouring system Ordinary runner system, also called runner system, or pouring system, is the necessary passage for molten plastic from the nozzle of the injection machine to the mold cavity. The runner system includes main runners, runners, gates, etc. Mainstream:Also called the main runner, sprue or down runner, it refers to the runner from the part where the nozzle of the injection machine is in contact with the main runner bushing of the mold to the runner. This part is the first part where the molten plastic flows through after entering the mold.

Mold material selection is a very important link in the entire mold making process. Mold material selection needs to meet three principles: The mold meets the work requirements of wear resistance, strength and toughness; The mold meets the process requirements; At the same time, the mold should meet the requirements of economic applicability. The mold meets the requirements of working conditions

The plastic injection mold production process is generally divided into: customer customization, mold design, mold manufacturing, mold inspection and testing, mold modification and repair, mold maintenance, and I will explain them one by one below. Customer Customization In the production of plastic molds, customer engineers first provide product drawings to the mold manufacturer. The manufacturer collects, analyzes, and digests product data through the task requirements of molded plastic production, which is customized for customers.

The-Increase-And-Decrease-Technology-Of-Prototype-Production
CNC machining and 3D printing are both processing technologies that have received much attention in recent years. CNC is subtractive manufacturing and 3D printing is additive manufacturing. Although these two processing technologies are very different at the production level, they are both used in production. Before the product model is used for verification, how should companies choose between the two mature model production processes, 3D printing and CNC processing, if they want to make prototypes? 3D printing can process multiple parts at one time, directly import 3D data maps, and generate data through calculations. Computer data can be directly transmitted to the machine for printing. During this period, no personnel is required to operate, only the operating room is constant temperature and humidity throughout the day. Read more
