Injection molding process is not static, logical, because of the different products, different materials, different injection molding machine and material preparation and so on the different conditions, injection molding process will produce many uncertain factors, so as the injection molding processing workers, according to specific conditions to the corresponding process optimization adjustment is the highest embodiment of injection molding processing technology. Therefore, the processing optimization of injection parts of sensor copper nut +ABS can be carried out from the […]
Low glossiness means that the surface is dark and dull, and the transparency of transparent products is low. There are many reasons for poor glossiness. Generally, the surface gloss defects of products can be divided into three types: plastic mold failure, improper forming conditions and improper use of raw materials.
Injection Mold Failure
Because the surface of plastic parts is the reappearance of the cavity surface of plastic mold, if there are scratches, corrosion, micro-holes and other defects on the surface […]
Why do injection products flash? Flash burr may occur during injection molding, which is largely due to the failure of mold or machine clamping force. It affects the quality of the product, we need to understand the cause of flash.
Why do injection products flash?
The material temperature is too high
For low viscosity melt materials such as polyamide, if only by changing the molding conditions to solve the spillage defect is very difficult, spillage, should consider appropriate to reduce the […]
When we have a project that needs plastic injection parts, the first thing we need to do is to find a plastic mould company to manufacture moulds and parts. But before we start, we need to estimate the cost of injection moulds and plastic moulds roughly and cost control. Here are some cost-saving suggestions for you. There are advantages and disadvantages. By reading this article, you can choose the right one according to the project requirements.
What is a multi-cavity […]
Injection mold is a common mold, polishing quality requirements and products are closely related to the scope of application. Therefore should understand the injection mold parts surface polishing requirements.
1) The inner surface of injection mold parts is usually not polished except for transparent parts. However, knife marks and spark marks are not allowed on the surface of mold cavity. The roughness of die surface directly affects the roughness of plastic part surface. The polishing has the ordinary polishing glossy […]
When you search for “Plastic Mold Manufacturer” or “Plastic Mold Factory” on Google, you will get a lot of information and contact information about the mould manufacturers. How can you find a suitable supplier in this huge information?
roulette recommends you send RFQ to five or more suppliers of plastic molds. Then you can compare the prices of suppliers, their reaction speed and their professional level. Usually, the plastic mold manufacturer will arrange engineers or salesmen with engineering background to contact […]
Use pure resin
In many plastic parts, especially in polyvinyl chloride, styrene, polyethyl acetate and acrylate plastics, a small amount of monomer residue will produce unpleasant odors, which can be removed by resin with monomer residue.
The catalyst tertiary amines used in the production of polyurethane foams often produce very weak odors and fog the car Windows. The solution is to find alternatives to these amines: use polyhydroxyl compounds, which are not only components of the polyurethane molecular chain […]
In the process of mould making, it is very important and difficult to find the position of flow balance in the design of runner. In the past, it is often necessary to design runners through past experience to achieve the goal of flow balance, so it needs continuous practice to find solutions, which will lead to longer product development time and increased cost. Mould flow analysis can assist runner design, shorten product development time and find potential problems easily, so […]
Many china companies can offer custom plastic injection molding services, but those that are certified generate undoubtedly much more confidence.
Although there are not so many companies dedicated to providing custom injection molding services, it is true that most do not have an international certificate that gives them confidence and reliability to all future clients.
roulette only offers high-end products, and completely ensures its durability and functionality.
There is a manufacturer that has certificates that indicate that the products are of the […]
