In modern industrial manufacturing, the epoxy resin casting process is a core link in the production of high-performance insulating components such as transformers and dry-type transformers. The static mixing vacuum casting equipment, through fully automated and high-precision technical design, has completely solved the pain points such as residual bubbles, unbalanced proportions and low efficiency in traditional casting, and has become a key equipment for improving product reliability and production efficiency.
I. What is static mixing vacuum casting equipment?
is an advanced device that integrates a static mixer, vacuum degassing system and automatic control. It achieves bubble-free and high-precision casting and molding of materials such as epoxy resin through raw material pretreatment, precise measurement and static mixing in a vacuum environment. Compared with traditional manual mixing, this technology does not require dynamic mechanical stirring. It achieves uniform mixing by relying on the flow diversion and collision of fluids inside the pipeline, fundamentally avoiding the problems of bubble introduction and uneven material curing.
Ii. Core Advantages of the Equipment: Why is It the top Choice for Industry Upgrading?
Outstanding product quality
Zero-bubble molding: Mixing and pouring are completed in a vacuum environment (with a vacuum degree of less than -0.095MPa), completely eliminating the bubbles generated during material stirring and reaction, allowing the epoxy resin to closely adhere to the mold, and the formed parts have higher electrical insulation and mechanical strength.
Precise proportion control: Through the vacuum batching device of the electronic scale and the automatic metering system, the proportion error caused by temperature drift and pressure difference is solved, ensuring the complete curing of the two-component materials and avoiding non-curing and performance degradation.
Significant economic benefits
Shorten the R&D cycle: During the trial production of new products or small-batch production, this equipment can quickly complete the prototype pouring, helping enterprises accelerate product iteration. For instance, a certain military industrial enterprise utilized a vacuum injection molding machine in conjunction with silicone molds to pour impellers, thereby enhancing the high-speed resistance of its products from 30,000 revolutions per minute to 100,000 revolutions per minute and promptly completing a critical task.
Reduce overall costs: Automated processes reduce reliance on manual labor, avoid material waste, and simultaneously lower costs through high pass rates. Actual cases show that after adopting the static mixing process, the qualification rate of epoxy cast insulating parts increased by 7.8%, and the comprehensive production cost decreased by 14%.
Full automation and flexibility
Intelligent control: The equipment adopts a single-chip microcomputer or PLC system to continuously adjust the stirring speed, vacuum degree and pouring speed, and is suitable for different material formulas.
Modular design: Supports rapid switching of molds and process parameters to meet the production requirements of multiple varieties and small batches, such as the rapid production transfer of electrical products like dry-type transformers and high-voltage switch insulators.
Iii. Typical Application Scenarios
Electrical and electronic industry: Epoxy insulating parts casting for dry-type transformers, current transformers, and arc suppression coils.
New energy and automobiles: Vacuum resin pouring for lithium battery insulation structural components and ignition coils.
Military industry and aerospace: Forming of complex structural components such as high-precision impellers and missile fuse devices.
