Please leave the repair and maintenance of old products to Harada Ironworks.
What the customer requested was our in-house jig.
Unfortunately, the product had been used for many years, resulting in peeling paint and advancing rust. This jig was old, and there were no existing drawings, so new production would require time and budget.
Therefore, we only performed modifications and repairs on the necessary parts, along with repainting. First, we removed the paint and rust using blasting (Type 1 surface preparation) and conducted surface treatment. After that, we applied a primer and topcoat, completing the product.
This product measures 1500×1500 L=2500, and we used grid blasting, performing surface preparation according to SSPC SP-10. Additionally, we applied one coat of epoxy-modified alkyd resin primer and one coat of synthetic resin blended paint for the topcoat.
The repair and modification took only four days. It took a bit longer due to the need to differentiate the painting of the main frame and the handrails and ladder, but we were able to accommodate the short delivery time.
After blasting, the painted product became remarkably clean and its durability improved.
