What Are the Factors that Affect the Quality of Mold Accessories

  Mold accessories are mainly parts or components installed on the mold. They can be widely used in various plastic molds, stamping molds, automobiles, electrical and aviation manufacturing fields. However, for mold accessories, the better the quality, the longer the life. Therefore, it is a problem that we all pay close attention to to understand the factors that affect the quality of mold accessories. Do you know what factors affect the quality of mold accessories? Hairong Precision introduces you below:Hope for the future plastic mould part manufacturer It can achieve rapid and stable development and serve social development and people’s needs well. https://www.dghrjmmj.com

  

  

  The factors that affect the quality of mold accessories are as follows:

  

  1. Rationality of mold accessory design

  

  Mold accessory designers should first fully understand the user’s use requirements and working conditions, and the situation of die-casting force, and then select suitable materials according to the use requirements and working environment, and understand the die-casting performance of the materials. In the design of mold accessories, special attention should be paid to the premise of meeting the use requirements, and the die-casting structure should be as simple as possible. The wall thickness should be appropriately uniform, and the necessary mold slope should be left, otherwise it will cause pits, pores, shrinkage, underpressure, stretch marks, cracks, deformation and other defects on the casting. The requirements for the dimensional accuracy of the casting should be reasonable, otherwise it will bring unnecessary troubles to the mold design, mold processing, process condition formulation and management, and will cause a large number of unqualified products.

  

  2. Mold structure, processing accuracy and mold material

  

  The selection of mold accessories for die casting is closely related to the product quality of die casting, mold design, processing, mold material selection, etc. If the mold structure is unreasonable, it is difficult for mold accessories to make the product qualified no matter what measures are taken from the process. In addition, the mold material, mold processing accuracy, surface roughness, processing marks, small cracks in heat treatment, nitride layer thickness and mold assembly of heat-resistant and wear-resistant mold accessories will affect product quality and mold life.

  

  3. Shrinkage rate of mold accessories

  

  The shrinkage rate of casting materials is generally expressed as an average percentage or a percentage of a certain range of variation. The average shrinkage rate of the material is usually selected. For the design of high-precision die castings and molds of mold accessories, special attention should be paid to the selection of material shrinkage. If necessary, the mold can be tested first, the required data can be obtained in the test mold, and then the production quantity of large molds designed and manufactured can be carried out.

  

  To sum up, these are the factors that affect the quality of mold accessories. In order to better ensure the quality of mold accessories, we try to choose the best structural solution in the design process. The designer of mold accessories must fully consider the technical requirements and structure of the parts, and must meet the processability and feasibility of mold manufacturing.

How Does a Metal Core PCB Improve Heat Dissipation

  Metal core printed circuit boards (MCPCBs) are an essential innovation in electronics, designed to address the challenges of heat management in high-performance applications. Unlike traditional PCBs, which use materials like FR4, metal core PCBs incorporate a metal layer!typically aluminum, copper, or a metal alloy!within the board. This metal core plays a crucial role in improving heat dissipation, ensuring the reliable operation of electronic components.As a representative of the industry, professional pcb manufacturer It is necessary to set a certain example for peers and lead the way in product quality. https://www.hongmycircuits.com/

  

  The Role of the Metal Core

  

  The primary function of the metal core in a PCB is to act as a heat sink. When electronic components generate heat during operation, this heat must be efficiently removed to prevent damage or performance degradation. The metal core, with its superior thermal conductivity, absorbs heat from the components and spreads it across the surface of the board. This prevents localized hotspots, which can lead to overheating and potential failure of components.

  

  Thermal Conductivity and Heat Transfer

  

  Aluminum and copper are commonly used metals in MCPCBs due to their excellent thermal conductivity. For instance, aluminum has a thermal conductivity of around 205 W/mK, while copper¨s thermal conductivity is even higher at approximately 400 W/mK. These properties allow the metal core to quickly transfer heat away from critical components, reducing the thermal resistance between the heat source and the surrounding environment.

  

  In a typical MCPCB, the metal core is placed directly beneath the insulating dielectric layer, which in turn lies under the copper circuit layer. When heat is generated by the components, it passes through the dielectric layer and is absorbed by the metal core. From there, the heat is distributed evenly across the board and dissipated into the air or a heat sink.
