Technology
The large cyclone separator uses centrifugal force to separate overspray powder from the air stream; combined with rotary-wing reverse-pulse two-stage filter recovery, the powder is sieved and blended back into the powder hopper in proportion for reuse, giving an overall utilization rate above 90% and a substantial direct reduction in material costs.
Grating contour detection and laser 3D scanning build a workpiece model, from which the system automatically generates the spray path; each spray gun has its own servo drive, so blind spots are compensated automatically and complex workpieces depend far less on manual labour.
The longer and heavier the workpiece, the greater the demands on rail load capacity and cycle time synchronisation. An I-beam rail offers higher load capacity and suits heavier workpieces, while a power-and-free system uses switches and hoists to synchronise cycle times and makes extremely efficient use of floor space.
Powder coating itself emits no volatile organic compounds (VOC). As dry-processing equipment, the large cyclone system produces no wastewater or waste residue; the overspray powder collected is solid waste that is easy to handle, meeting the strictest environmental requirements.
Pre-degreasing, degreasing, rinsing, conditioning, phosphating, rinsing, passivation and drying: the bath concentration, temperature and time of every stage affect the quality of the phosphating film. Pre-treatment is the key process that determines coating adhesion and corrosion resistance.
From the early vibrating-sieve powder hopper, to the simple powder feed center with dust-collection hood, to the standard lifting pump table powder feed center, and on to the Wagner super powder feed center, the Gema powder feed center and the KCI premium powder feed center, every upgrade in powder feeding has improved the powder utilization rate and colour change efficiency.
Company News
The line uses a vertical aluminium profile conveyor: workpieces run flat up an incline and then hang vertically for spraying, and unloading levels them on an incline for easy removal and stacking. Combined with a large cyclone rapid colour change powder coating booth, it supports continuous production with frequent multi-colour changes.
The system is equipped with laser 3D scanning and QR code workpiece identification, so the controller can automatically call up the coating program for the relevant workpiece and set the spray gun and reciprocator parameters, greatly shortening changeover time.
The new website reorganises the product catalogue around the coating process flow and adds a Digital Twin & MES Integration section, making it easier for customers to understand Shihong's products and service capabilities.
The heat cleaning furnace decomposes the organic coating on jigs at high temperature in an oxygen-deficient atmosphere without damaging the metal substrate, helping the customer reuse jigs, greatly reducing consumable costs and maintaining powder deposition efficiency.
