There are many reasons that lead to the bursting of the metal stamping template. From the purchase of raw materials for the metal stamping die to...Read more -
Causes and Solutions of Side Wall Dents of Injection Molded Parts
“Dent” is caused by local internal shrinkage after gate sealing or lack of material injection. The depression or micro depression on the surface of injection molded parts is an old problem in the injection molding process. Dents are generally caused by the local increase of shrinkage...Read more -
Important Processes Affecting the Strength of Injection Molded Parts
Injection molding machine (injection molding machine or injection molding machine for short) is the main molding equipment that makes thermoplastic or thermosetting materials into plastic products of various shapes using plastic molding molds. Injection molding is realized through injection moldi...Read more -
Causes and Measures for Brittleness of Large Injection Molded Parts
According to the molding theory, the main reason for the brittleness of injection molded parts is the directional arrangement of internal molecules, excessive residual internal stress, etc. If the injection molded parts have water inclusion lines, the situation will be worse. Therefore, it is nec...Read more -
What are weld lines?
Weld lines are the most common among many defects of injection molded products. Except for a few injection molded parts with very simple geometric shapes, weld lines occur on most injection molded parts (usually in the shape of a line or V-shaped groove), especially for large and complex products...Read more -
How to distinguish between mould oil stain and material oil stain on plastic parts?
We know that the products with oil stains on the mold are basically waste products. Most of the mold oil stains are more than 80% of the time, but there will still be 10% – 20% of the mold oil stains. The so-called mold oil stains are not in the mold, but in the materials.For example, some ...Read more -
Cause and solution of Glue inlet air mark in PC material
In case of air lines or jet lines near the rubber inlet of injection molded parts during production, the following analysis can be referred to for comparison and improvement. Among them, reducing the injection speed is the primary means for us to improve the problem of injection lines and air lin...Read more -
What are the common injection mold materials?
Common injection mold materials are chemically and physically divided into acrylate, styrene and styrene. Each monomer has different characteristics: acrylate has high strength, thermal and chemical stability: from the morphological point of view, the polymerization of three monomers produces thr...Read more -
What are the application fields of injection mold?
Injection mold is an important process equipment for the production of various industrial products. With the rapid development of plastic industry and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, ships, automobiles and other industrial sectors,...Read more -
Precautions for Polishing of Injection Mold
Injection mold polishing has two purposes; One is to increase the smoothness of the mold, so that the surface of the products produced by the mold is smooth, beautiful and beautiful. The other is to make the mold easy to demould, so that the plastic will not be stuck to the mold and cannot be det...Read more -
What are the difficulties in manufacturing injection molding?
The plastic injection molding process must first be the injection mold. If it is a simple injection molding part, the mold is relatively easy to manufacture, such as injection Mold for Pulley. If the injection molding parts with complex structure are encountered, the injection molding manufacture...Read more -
Three Factors Of Poor Gloss Of Injection Molding Products
Many injection molding manufacturers will encounter similar problems. There is no problem with the product quality, but the product gloss is really unqualified, which eventually leads to scrap products after the processing of injection molded parts. In addition to the problems of the plastic itse...Read more -
How to Solve the Odor of Injection Molding Products？
Injection molding manufacturers purchase qualified plastic particles, which is an important guarantee to ensure that injection molding products are free of odor. As for some plastics, which have certain odor, injection molding manufacturers need to take certain measures before production. Injecti...Read more -
What is a weld crack?
What is a weld crack? It is the most common serious defect in weldments. Under the joint action of welding stress and other brittleness factors, the bonding force of metal atoms in the local area of the welded joint is destroyed and a new interface is formed. In welding technology, we should avoi...Read more -

Influence of mold temperature, melt temperature and injection speed on product shrinkage
1、 Two temperature conditions that are not conducive to solving the shrinkage problem 1) The mold temperature is too low, which is not conducive to solving the shrinkage problem The shrinkage problem of hard rubber parts (surface shrinkage and internal shrinkage) is a defect caused by the space ...Read more -
Correct mold cleaning may be an effective way to solve burrs
Flash of parts may occur due to various reasons, from changes in process or materials to tooling failures. Burrs will appear on the edge of the part along the parting line of the mold or anywhere where the metal forms the boundary of the part. For example, plastic electrical shell, pipe joint, pl...Read more -
