What Is The Main Flow Of Plastic Mold? The main runner refers to the section from the contact part of the injector nozzle and the mold to the branch runner. Design considerations: (1) The end face of the sprue is usually circular. (2) In order to facilitate demoulding, the main runner is generally made with a slope. However, if the main runner passes through multiple plates at the same time, pay attention to the slope
Three Precautions for Plastic Mold Making First,Don’t just focus on product design and neglect plastic mold manufacturing. When developing products or trial production of new products, some users tend to focus on product development and development at the initial stage, ignoring the communication with plastic mold manufacturers. After the preliminary determination of the product design scheme, contact with the mold manufacturer in advance has two advantages: 1. It can ensure that the products designed
Cause and Solution of Plastic Product Brittle What are the reasons and solutions for product brittleness during injection molding? After injection molding, the impact performance of plastic parts has decreased significantly compared with that of raw materials, which is commonly known as brittleness. The direct cause of brittleness is the excessive internal stress of plastic parts. 1. Material Before injection molding, set appropriate drying conditions. If the materials are dried for several days or the
How can plastic mold manufacturers effectively improve production efficiency? In the era of rapid development of industrialization, how to improve the production efficiency, shorten the development cycle, improve the technical level of plastic mold, reduce production costs and other factors is undoubtedly a problem faced by plastic mold factories at this stage. 1. Implement concurrent engineering throughout the process. The whole process of concurrent engineering is one of the most effective ways to shorten the
How to effectively improve the mold precision management during mold processing. First of all, we must know which factors affect the processing accuracy of injection mold. The main factors affecting the die precision are as follows. (1) Precision of product parts The higher the precision of product parts, the higher the precision of mold working parts. The mold precision not only has a direct impact on the precision of product parts, but also has a
Reasons for the appearance of flaring edge in the processing of injection mold Many staff hate products with more fins, because there are more processes to be processed in the later period, and they prefer products without or with less fins, because they can be put into the finished product area after being processed, making their work easier! There are 4 places where the plastic injection mold is prone to flaring 1. Flare of parting
Factors Affecting the Quality of Injection Mold Mold manufacturing is a complex process. From design, processing, assembly, debugging and other steps to the final real use, in the entire life cycle, the factors that affect mold quality mainly include the following 10 aspects. 1. Die steel Steel is the decisive factor of mold quality, and selecting reasonable steel is the top priority. The criteria for steel selection are: ① Requirements for injection molding materials
Processing technology standard of rubber mould 1. Purpose and Scope of Application This standard is formulated to ensure the rationality and consistency of rubber mold manufacturing and processing technology, optimize the processing technology, and improve the progress of mold manufacturing. 2. Die processing process standard 2.1 Process preparation: 2.1.1 Process preparation requirements: specify the processing reserve, reserve orientation, roughness requirements and precautions in the process. 2.1.2 Compilation principle of processing flow: on the premise of
Why should the injection mold be tested after processing After the injection mold is processed, the mold test is the last step to check whether the mold can produce qualified products. It can be said that mold trial is a comprehensive inspection of our mold development and design, and the results of mold trial will directly affect the production and quality of the factory products. Why should we try the mold? Mold is a precision
Several Practical Tips For Mold Tooling To Reduce Defects! In order to improve the use performance of the mold, many manufacturers will properly process their molds. Mold processing refers to the processing of the forming and blank making tools, and also includes the shear mold and die cutting mold. However, in many cases, the mold processing will also reflect the processing defects, leading to the decline of the mold performance. How to build mold processing
Common steel materials and their characteristics in mechanical and die processing Leading the mechanical frontier, mechanical video, automobile, processing technology, 3D printing, automation, robot, production process, bearing, mold, machine tool, sheet metal and other industry frontiers are waiting for you here 1. 45 – High quality carbon structural steel, the most commonly used medium carbon quenched and tempered steel Main characteristics: the most commonly used medium carbon quenched and tempered steel has good comprehensive
What Is “mold making”? Mold Making refers to the processing of forming and blank making tools, in addition to shear molds and die cutting molds. Generally, the mold consists of upper mold and lower mold. Place the steel plate between the upper and lower molds, and realize the forming of materials under the action of the press. When the press is opened, the workpiece determined by the mold shape will be obtained or the corresponding
Main advantages of TPE applied to adhesive coating TPE adhesive coating refers to coating TPE soft adhesive material onto other materials. Generally, the processing methods used are two-color injection molding machine for one-time molding or general injection molding machine for secondary injection molding using rubber coated mold. TPE plastic coated products are generally handles and handlebars. Because of the special comfortable touch of TPE soft adhesive material, the introduction of TPE material has improved the
Solutions to common overmold injection defects Lack of glue – increase the processing and injection molding temperature; Increase injection pressure; Improve material flow. Splitting and overflow – reduce the injection temperature; Increase the clamping force; Reduce injection pressure; Reduces fluidity from the formulation point of view. The surface is pitted and not bright – increase the injection molding processing temperature; Bake materials to reduce moisture of raw materials. Poor viscosity – sufficient drying
Notes on the design of two-shot mold and overmold 1、 Two shot mold A mold in which two plastic materials are injected on the same injection molding machine and molded twice, but the product is only molded once. Generally, this molding process is also called double material injection molding, which is usually completed by a set of molds and requires a special two-shot injection molding machine. 2、 Overmold (secondary molding) The two plastic materials are not necessarily injected
