Even if I have been repairing hydraulic injection molding machines for many years and I am quite confident in maintenance technology, using the experience of repairing hydraulic injection molding machines in the past to repair all-electric injection molding machines will feel powerless when working.... read more
The requirements of injection molding machines for the production of small and light parts have made thin-wall injection molding machines the required performance for injection molding machines. "Thin wall" is generally defined by lightweight electronic device parts with a wall thickness of less tha... read more
High-speed production of vertical injection molding machines requires large thin-walled speeds; we need speed curves for thick-walled parts to avoid some defects; to ensure that the quality of the parts meets the standards, the injection speed should be set to keep the flow rate of the melt forward ... read more
As the plastic flows through different parts of the injection molding machine and the mold, due to the influence of resistance and friction, the pressure on the plastic flow front will be lost. In addition, as the plastic contacts the mold wall, it begins to cool, increasing the viscosity of the pla... read more
The insert molding of the rotary table vertical injection molding machine refers to the molding method of inserting pre-prepared inserts of different materials into the mold and injecting resin. Basically, injection molding refers to the method of inserting injection-molded parts on a part of the me... read more
What are the product characteristics and characteristics of vertical injection molding machine? The vertical injection molding machine is controlled by a microcomputer. The power system is driven by hydraulic pressure. The plastic is heated in the material tube by the electric heating ring and the m... read more
1. General performance: BMC injection molding machine mold plastic (DMC) has a large proportion between 3-2.1; the product has a bright appearance, good hand feel, and a hard and heavy feeling; heating with fire will produce a large amount of oil smoke and styrene odor; Some varieties of BMC mold pl... read more
Among the current four transmission methods (mechanical, electrical, hydraulic and pneumatic), none of the power transmission methods is perfect. The hydraulic transmission of BMC injection molding machine has the following obvious advantages: (1) From the structural point of view, the output power ... read more
Different types of injection molding machines1. Different types of injection molding machines Plastic bottle forming machines can usually be divided into two categories: one uses a single-stage hot preforming method and the other uses a two-stage cold preforming method. In a single-stage machine, th... read more
Crusher and its type Crusher type Crushers are divided into three categories according to their crushing stage. They are (i) primary crusher, (ii) secondary crusher and (iii) tertiary crusher. The primary crusher receives materials directly from the mine (ROM) after sandblasting and reduces the size... read more
What industrial chillers are used forIn an ideal cycle, the condenser plays a dual role. Before any condensation occurs, the high-pressure steam must first be saturated (desuperheated). Sufficient heat must be transferred from the refrigerant to lower its temperature to saturation temperature. At th... read more
Injection mold manufacturingCompound design, EDM injection mold manufacturing Plastic injection molds are usually made of hardened or pre-hardened steel, aluminum and / or beryllium copper alloy. Steel molds are more expensive, but are often preferred because of their high durability. The hardened s... read more
