Craftsmanship and Intelligent Manufacturing Empower Precision Casting Upgrades | New Four-Column Dual-Station Wax Injection Machine Officially Put into Production, Reshaping the Standards of Wax Pattern Production Our company's independently developed and upgraded four-column dual-station wax injection machine has successfully completed overall debugging and entered mass production. This core forming equipment, designed for the investment casting industry, leverages three core advantages—a stable four-column load-bearing structure, dual-station alternating operation, and an intelligent digital control system—to solve industry pain points such as unstable precision, low production capacity, and high reliance on manual labor in traditional wax injection processes. It lays a solid foundation for the upstream processes in the production of high-end castings for aerospace, automotive parts, precision hardware, and medical devices.
I. Rigid Four-Column Structure, Building a Solid Foundation for Long-Term Stable Operation
The equipment adopts a thickened steel plate integrated welded body, combined with four high-strength precision guide columns and a vertical hydraulic drive unit, forming a balanced and stable four-column pressing structure. Compared to traditional single-column or C-frame machines, the four-column layout evenly distributes mold-closing pressure, preventing table tilting and mold misalignment even under prolonged high-pressure operation. This ensures consistently stable mold-closing accuracy, effectively eliminating defects such as flash, material shortages, and dimensional deviations in wax molds, significantly extending mold lifespan. It is suitable for large-tonnage, large-size wax mold pressing and molding applications.
The machine integrates an independent dual-station operating platform. The two stations operate completely independently, enabling seamless production by simultaneously performing wax injection and pressure molding while demolding/molding replacement. This eliminates the time wasted waiting for cooling and downtime for mold changes associated with single-station machines, increasing overall production cycle time by over 40%. A single person can manage both stations in rotation, significantly optimizing labor costs. The integrated material storage and receiving trough at the bottom automatically recovers overflowing wax, reducing raw material waste and promoting both clean production and energy conservation.
II. Intelligent CNC Control for Micron-Level Precision Control of Wax Models
This machine is equipped with a touch-screen PLC intelligent central control system, allowing for fully visualized parameter settings throughout the entire process. Two workstations can be independently configured with wax injection pressure, injection speed, holding time, and temperature control curves, accommodating waxes of varying hardness and various mold specifications. The equipment features independent temperature control modules, keeping wax temperature fluctuations within ±0.5℃. Combined with a uniform-speed, pressurized injection process, this ensures the molten wax evenly fills the mold cavity, preventing air bubbles, shrinkage cavities, and deformation defects within the wax model. Wax model dimensional consistency accuracy reaches ±0.05mm, perfectly matching the stringent pre-process requirements of high-end precision castings.
The entire hydraulic and pneumatic power system has undergone noise reduction optimization, resulting in low vibration and a low failure rate. It supports 24/7 continuous operation, adapting to large-scale assembly line production. Interfaces for automation upgrades are also reserved, allowing integration with robotic loading/unloading and automatic release agent spraying modules, helping companies gradually build fully automated, unmanned wax injection production lines.
III. Full-Scenario Adaptability, Boosting High-Quality Development of the Precision Casting Industry
This four-column, dual-station wax injection machine has quickly covered the manufacturing needs of multiple fields since its deployment: in the new energy vehicle sector, it is used for wax model making of turbine housings and precision gearbox components; in the aerospace sector, it meets the high-precision investment casting needs of small blades and structural parts; and it is also widely used in investment casting processes in industries such as stainless steel hardware, plumbing fittings, high-end handicrafts, and medical implants.
The equipment R&D leader stated that in the future, they will continue to focus on the R&D of equipment for the entire precision casting process, building complete intelligent production lines around upstream and downstream processes such as slurry application, sand application, firing, and smelting. They aim to use core equipment technology to help the domestic casting industry transform from traditional extensive processing to high-precision, automated, and green intelligent manufacturing, continuously providing equipment solutions for the localization and upgrading of the manufacturing industry.
