Process Upgrade to Consolidate Quality Foundation of Instrument Products
As a professional manufacturer of instruments and meters, the rust removal, oxide scale elimination and surface roughness enhancement of metal parts such as various valve bodies, flowmeters and instrument shells directly determine the sealing performance, corrosion resistance and dimensional accuracy of finished meters.
The newly introduced hook-type shot blasting machine adopts a fully enclosed working chamber paired with an independent high-power dust removal purification system. An electric hook automatically lifts batches of metal workpieces. Inside the sealed chamber, high-speed steel shots evenly strike workpiece surfaces to thoroughly remove casting oxide scale, forging rust and machining burrs in one single process, largely replacing traditional acid washing and manual grinding:
Doubled Processing Efficiency: Multiple batches of instrument valve bodies, connectors and shells can be processed in one lifting cycle, cutting manual polishing time by over 70% to meet the company’s mass processing demands for instrument components.
Enhanced Product Performance: Shot blasting treatment creates uniform compressive stress on metal surfaces, greatly improving the fatigue resistance and anti-corrosion capability of instrument parts. It fundamentally reduces risks of leakage and rust during later service, extending the service life of instruments and meters.
Stable Processing Consistency: Standardized mechanical shot blasting replaces manual operation to deliver controllable and uniform surface roughness for workpieces, providing a standardized base for subsequent spraying and assembly procedures and raising the factory pass rate of finished products remarkably.
Complete Eco Supporting System to Practice Compliant Green Manufacturing
The company has also installed an integrated closed dust removal pipeline system running synchronously with the shot blasting main unit to form a closed-loop dust control system.
The full set of equipment is equipped with a large-capacity bag dust removal cabinet and high-pressure centrifugal induced draft fan, with sealed spiral ventilation pipes laid throughout the workshop. Metal dust and oxide debris generated during operation are collected under negative pressure in real time, with a dust filtration efficiency complying with national industrial waste gas emission standards. No dust leakage or workshop fugitive dust occurs.
A full set of auxiliary air supply equipment including screw air compressors and air storage pressure stabilizing tanks is deployed in the workshop to guarantee stable and continuous operation of the shot blasting system. The entire production line operates in fully enclosed conditions, completely eliminating dust pollution caused by conventional open grinding, improving on-site working environments, meeting environmental inspection requirements and realizing standardized, clean metal surface processing.
Smart Manufacturing Upgrade Empowers High-Quality Corporate Development
Henan Felix Instrument & Meter specializes in the R&D and production of flowmeters, industrial valves and precision instruments, with continuous investment in intelligent and eco-friendly renovation of production equipment.
The launch of the eco shot blasting machine solves two core production pain points: low efficiency of component surface treatment and difficult pollution supervision.
On one hand, it optimizes the full industrial production chain, breaking capacity bottlenecks covering casting rough machining, precision shot blasting, finish machining and finished assembly. This helps the company expand independent processing capacity of instrument parts and shorten order delivery cycles.
On the other hand, the green equipment transformation fulfills the company’s environmental protection responsibilities. While strictly controlling pollutant emissions, it elevates core processing technology and strengthens the market competitiveness of the company’s full range of industrial precision instruments and meters.
Moving forward, Henan Felix Instrument & Meter will keep advancing intelligent and eco-friendly renovation of production workshops. By leveraging advanced processing equipment to optimize production techniques, the company will deliver more stable and reliable precision instrument and meter solutions for oil & gas, chemical, water treatment and other industries with high-quality, eco-conscious manufacturing capabilities.
