There are two main purposes of polishing the mold. One is to increase the brightness and appearance of the plastic mold. The second is to make the mold easy to demold. When polishing, rough oilstone is generally used to roughen the surface of the machined mold cavity to remove the knife marks of the machine […]

In the process of mold processing, what annoys you most is some common defects, these defects will directly lead to the performance of the workpiece, and even make the workpiece unable to be used here, so we must try to avoid some defects when we are processing the mold , Here are seven magic weapons

Injection mold is a tool for producing plastic products. In order to meet the needs of molded parts, we need to pay attention to some things when choosing injection molds and put forward corresponding requirements. The following six requirements need to be met to choose a more suitable injection mold. 1. High corrosion resistance. Many

There are often failures in the use of molds. Starting from the actual situation, we will focus on several failure methods. There are mainly the following five types: plastic deformation failure; wear failure; fatigue failure; cold and heat fatigue failure; failure under the influence of comprehensive factors. (1) Plastic deformation failure The main reason is

1. Methods to prevent quenching cracks (1) Reasonably design the shape of parts. Try to use equal wall thickness design to avoid sudden changes in cross-sectional shape: ①Don’t make parts with large wall thicknesses into one piece, but use a mosaic structure so that each piece has the same strength as possible; ②The thick parts

In the production of aluminum alloy die-casting, the most common way of mold damage is cracks and cracks. Stress is the primary cause of mold damage. In the process of die casting production 1. Mold temperature The mold should be preheated to a certain temperature before production. Otherwise, chilling occurs when the high-temperature molten metal

1. Extrusion honing machine: used to fix the parts and fixtures in the specified position, and apply squeezing force to the grinding abrasive. The extrusion honing machine has two opposing abrasive cylinders. When closed, the parts or fixtures are clamped to squeeze the abrasives from one cylinder to the other. The constrained parts of the parts

A good blow moulded part starts from the design. The design of blow-moulded parts of plastic containers is the key to manufacturing competitive and high-quality containers. It is a systematic and comprehensive engineering plan. That is, first consider meeting the use function; then select the material and determine the blow moulding method (particularly pay attention to

Compared with machined gears, injection-moulded gears have almost nothing in common except for the use of involute conjugate to transmit motion. These two types of gears are essentially different. Machining gears are cut to a specified size on a special gear machine designed for specific processing tasks; injection-moulded gears are injection moulded in a gear

Gear injection moulding process Various injection moulding processes and injection moulding machinery are not the same. Gear injection moulding technology requires high accuracy and repeatability. Generally speaking, high-precision gears need to be made of new resin. But even if the new resin is used, the material must still have a suitable degree of dryness, its
