Analysis of Graphite Mold Products

Graphite molds are suitable for precious metal melting and forming, chemical anti-corrosion product processing, electronic and electrical component shaping, and are also widely used in photovoltaic thermal field components, new energy electrodes, 3C precision components, vacuum high-temperature equipment and other scenarios. The structure is sturdy and not easy to crack or deform, the demolding is smooth and the reuse frequency is high, and the service life is long. It is a high-end high-temperature resistant precision forming accessory commonly used in metallurgy, machinery, electronics, photovoltaics, new energy and other industries.

Our company combines the development trend and market demand structure of the entire graphite shaped mold industry chain, and the industry procurement and cooperation mainly focus on two core main lines: deepening the traditional industrial field, becoming a well-established leading enterprise in graphite shaped molds with large production capacity and stable supply channels; Layout high-purity, precision, and special graphite shaped molds, deeply bound to high-quality photovoltaic and semiconductor customers as a growing enterprise.

Graphite shaped molds are matched according to their usage scenarios, including general working conditions such as daily ordinary workpiece pressing, medium and low temperature forming, and conventional mechanical processing. Choosing ordinary industrial graphite shaped molds can meet the usage needs; High temperature environments such as high-temperature die-casting, powder metallurgy sintering, and vacuum high-temperature forming should prioritize the use of high-temperature resistant and heat-resistant modified graphite molds; High purity and high-density special graphite shaped molds must be selected for high-end fields such as photovoltaic thermal fields, semiconductor carriers, and new energy precision device molding; Select corrosion-resistant graphite molds for product molding under strong corrosion conditions in chemical engineering. Check the core physical parameters: prioritize verifying the purity of graphite. It is recommended to use high-purity graphite molds for high temperature, precision, and high cleanliness working conditions. The mold has low impurity content, is not easily damaged by high temperature oxidation, and will not contaminate the formed workpiece; Next, let's look at the bulk density. The higher the density, the denser the mold structure, and the stronger its wear resistance, compression resistance, impact resistance, and deformation resistance, resulting in a longer service life; Simultaneously confirm the thermal expansion coefficient and thermal conductivity, and select corresponding specifications of products based on the actual needs of equipment temperature control, conductivity, and insulation. Distinguishing production process and quality: The surface of high-quality graphite shaped molds is smooth and polished, the cavity and contour are regular, without cracks, pores, missing corners, powder falling and other defects, and the particles on the cut surface are uniform and delicate; After immersion, multiple roasting, high-temperature graphitization, combined with CNC precision machining and mirror polishing, the mold has better dimensional accuracy, sealing and self-lubricating properties, far superior to low-end molds with simple compression molding and rough machining; Prioritize selecting finished products with neat workmanship, precise dimensions, and small tolerance errors for easy on-site installation and workpiece forming. Select characteristics based on performance requirements: Emphasize maintenance free continuous operation, prioritize graphite shaped molds with strong self-lubricating properties, no need to add additional release agents, suitable for special scenarios such as closed equipment and precision molding; Long term outdoor, high-temperature and high-frequency cyclic use, identify graphite molds with added antioxidant technology to delay oxidation loss; For molding conditions that require high load bearing and compression resistance, choose high hardness, high-strength thickened graphite molds; For thin-walled, deep hole, complex curved and irregular structures, priority should be given to using specialized graphite materials with excellent toughness.
