A casting manufacturer in a certain location in Mexico was struggling with the surface cleaning of their iron and steel castings. The company produced components weighing up to 800kg each for the automotive and mining industries. Their existing manual cleaning method using chisels and grinders was slow, labor‑intensive, and produced inconsistent results. Rust and sand residues remained in cavities, leading to customer rejections.
The production manager needed an automated blasting solution that could handle various casting sizes and weights. After researching online, he discovered YG’s hook shot blasting machine. He wanted a spinner hanger shot blasting machine that could accommodate 800kg workpieces and integrate into his existing production line. YG recommended the YG378 model.
Technical Parameters Of The Hook Shot Blasting Machine
YG offers eight models of the machine. Based on the customer’s maximum workpiece weight (800kg) and size (1000×1600mm), YG selected the YG378. Below are key specifications:
| Item | YG376 | YG376B | YG378 | YG3710 | YG3720 | YG3730 | YG3750 | YG37100 |
| Maximum weight of cleaning(KG) | 500 | 600 | 800 | 1000 | 2000 | 3000 | 5000 | 10000 |
| Clean the workpiece size(mm) | 600*1200 | 700*1200 | 1000*1600 | 1200*1800 | 1400*2200 | 1600*2300 | 1800*2500 | 3000*3000 |
| Shot blasting amount (kg/min) | 2*200 | 2*200 | 2*250 | 2*250 | 3*250 | 3*250 | 4*250 | 5*250 |
| Lift (T/h) | 24 | 24 | 30 | 30 | 45 | 45 | 60 | 75 |
| Separator separation amount (T/h) | 24 | 24 | 30 | 30 | 45 | 45 | 60 | 75 |
| Power (KW) | 22.5 | 23.5 | 39.65 | 47.5 | 56.2 | 65.45 | 85.45 | 97.65 |
| Ventilation(m3/h) | 4000 | 4000 | 5000 | 5000 | 9000 | 11000 | 14000 | 16000 |
The YG378 machine features two blasting wheels, each delivering 250 kg/min of abrasive. This machine also includes a 30 T/h elevator and separator system for continuous abrasive recycling.
How Has This Hanger Shot Blasting Machine Improved Cleaning Operations?
The Mexican foundry installed the machine in its finishing department. The first test was on a batch of 600kg mining equipment castings. Results were impressive:
- Cleaning speed: The hook shot blasting machine cleaned each casting in under 4 minutes, compared to 30 minutes of manual grinding.
- Surface quality: The spinner hanger shot blasting machine achieved a uniform Sa 2.5 finish on all surfaces, including internal cavities.
- Labor reduction: One operator now loads and unloads the machine, replacing four manual grinders.
The machine also handles parts with complex geometries. The hanging system rotates the workpieces during blasting, ensuring full coverage. The machine has become an essential part of the foundry’s quality control process.
Customization For Mexican Foundry Conditions
YG engineers considered Mexico’s warm climate, the foundry’s abrasive dust environment, and local power specifications. Customizations included:
- Motor insulation upgrade to handle foundry heat and dust exposure.
- Electrical panel configured for Mexico’s 460V/60Hz power supply.
- Reinforced wear plates in the blasting chamber to withstand heavy castings.
- Automatic lubrication system to reduce daily maintenance time.
For the hook shot blasting machine, YG also provided Spanish‑language control labels and a detailed operation manual. The hanger shot blasting machine was shipped with a starter set of blades, control cages, and wear liners.
Tangible Results After Using The Hook Shot Blasting Machine
After three months of daily operation (8 hours/day, 5 days/week), the Mexican foundry recorded measurable gains:
- Cleaning output increased from 15 castings per day to 80 castings per day.
- Labor cost dropped by 60% – only one operator is needed for the machine.
- Rejection rate from surface defects fell from 18% to under 2%.
- Energy consumption per casting decreased by 40% compared to manual methods.
The spinner hanger shot blasting machine paid for itself in six months. The foundry has since ordered a YG376 model for smaller castings and is planning to add a second YG3710 for larger components.
Smooth Cooperation And Final Conversion
YG provided layout drawings and foundation requirements. Sea freight was arranged from China to Veracruz port, then trucked to the foundry. Remote video support via WhatsApp guided the electrical connection and wheel alignment. The machine came with a one‑year warranty and a comprehensive spare parts list.
