一. 基本理念:Basic opinion: 1. 什么是最佳的流动状态: What is the best flow state: 流体流动状态应该是喷泉状的,最佳的流动状态是流体前端的流动速度在型腔内处处相等。由于流动方向上截面积的不同,在其变化的位置应进行注射速度的调节 (注意:机床上所能设定的注射速度是指螺杆的前进速度)。 The flow state should be like fountain, and the best is that the speed of the front melt is the same everywhere in the cavities. For different are...

The plastic injection molding machine can complete the injection molding operation and notice the following points so that the safety of the production process and personal safety can be guaranteed. If the temperature of the large plastic injection molding machine rises, then the harm that this situation gives us is still very high. For exampl...

A scientific troubleshooter is not someone who pushes buttons faster or has more tricks up his or her sleeve. Rather, a scientific troubleshooter knows the history of a properly documented process, makes each adjustment based on knowledge, and verifies and documents the result of each change. Good troubleshooting does not begin when a non-conformance occu...

Injection molding machine maintenance is a just-as-important — though less-overlooked — component of the process. We’ll look at why maintenance for both injection molds and the machines that they run through is of great importance to you, your bottom line and the quality of your parts. What kinds of problems can occur in injection molds?&nb...

The usual plastic machinery is generally divided into two types, one is extrusion blow molding machine and the other is plastic injection machine. The extrusion blow molding machine extrudes the molten plastic through a fixed-shaped extrusion port under the action of a screw, and is cut by a water-cooled setting under the action of a traction ...

Extrusion blow molding machine is an important plastic machine. Most plastic products can be produced and manufactured by extrusion molding. Extrusion blow molding machine promotion and application value: (1) High efficiency and energy saving. The thermal efficiency is as high as 95%. Because it is directional heating, under the same condi...

The temperature rise of the injection molding machine is five major hazards: it causes the machine to produce thermal deformation, the viscosity of the oil decreases, the rubber seal deforms, and the oil accelerates the oxidative deterioration, and at the same time, the component pressure of the air is reduced. One of the hazards: mak...

In the process of purchasing a small injection molding machine, we must ensure that the performance and stability of the enterprise are better, and the reliability that can ultimately be achieved will also have better performance. Therefore, we must choose according to the actual situation, and the ultimate advantage that can be brought about is t...

It is very important to choose a good plastic injection molding machine. Do you know how? 1. Know the plastic components you intend to mould You Should Be Aware of the part: Vinyl substance Weight Typical wall section Gate place Maximum flow span from the gate Estimated bicycle period. Quality demand...

Before the horizontal injection molding machine starts up, the following points must be achieved: (1) Check if there is any lubricant (fat) in each active part and add enough oil. (2) Turn on the electric heat to warm the various sections of the barrel. When the temperature of each section reaches the required temperature, it is kept f...

Horizontal Injection Molding Machine is a widely used injection molding machine. Do you know its features? 1. Even if the mainframe is low in the fuselage, there is no height limit for the plant to be installed. 2. When the product can be automatically dropped, automatic molding can be realized without using a robot. 3, Due to the ...

Energy-saving of plastic injection molding machine can be divided into two parts: one is the power part, one is the heating part. Energy-saving part of the power: Most inverters are used, and the energy-saving method is to save the remaining energy of the motor. Heating part of the energy: Most of the heating part of the energy-savin...

Plastic molding Category: A injection molding: Plastic material is heated to melt in the heating cylinder injection molding machine, and then pushed by the reciprocating screw will melt to a method for closing a mold cavity in the molding. It not only can be obtained with high accuracy at high productivity, high-quality products, and processed plast...

The indications, guidelines and factors as well as all the different variations for use of a "cold runner" versus a "hot runner" are going to vary, and would range beyond the scope and ability to answer the question.  You will have to examine your application and choose accordingly, but I will try to explain briefly some of the advantages to a hot r...

Vertical injection molding machine   1, an injection device and a locking device for processing in the same vertical center line, and the mold is opened and closed down. Its floor area is only about half of the horizontal machine, so it is about two times as much as the floor area. 2, easy to insert molding. Because the surface of the die is upwards,...

The working principle of injection molding machine and injection syringe with similar, it is the use of screw (or piston) thrust, the plasticizing good molten state (i.e. viscous flow) plastic injected into the mold cavity closed good after curing stereotypes made the process of the products. Injection molding is a cycle process, each cycle mainly ...

When it comes to plastics processing tools, plastic injection molding machines are without a doubt one of the most versatile pieces of equipment, accounting for nearly 75% of primary plastics machinery. These invaluable machines can be used to make virtually anything, ranging from miniscule hearing aid parts to large individual parts like tractor hoods. &nb...
