The EU Construction Products Directive published in 2013 requires the use of stainless steel fasteners in exposed part of buildings which are expected to last for over 25 years. Earlier, construction fasteners were mostly in carbon steel and they can finish drilling, threading fixating and fastening in one process. While this saves time, it jeopardizes building safety due to long exposure and corrosion.
MIRDC (Metal Industries Research & Development Centre, Taiwan) said the construction fasteners sold on the market are mostly bi-metal self-drilling screws comprising carbon steel and stainless steel, possessing the hardness of carbon steel and corrosion resistance of stainless steel. However, they have a complicated processing procedure, and could potentially break apart on the welded spot or be corroded on the carbon steel section.
MIRDC developed a surface treating machine to handle anti-corrosion and surface hardening treatment for stainless steel parts, providing solutions to deficient stainless steel hardness, weakened corrosion resistance and inability of mass-production. The machine can make for a stainless steel surface hardness up to over HV1,200, much higher than with carbon steel and without undermining corrosion resistance.
Furthermore, the machine can batch process a large number of stainless steel parts. It can also handle complicated shapes and form an evenly hardened layer at the parts' surface. It uses an AI system for precise control of temperature, time and other parameters. Meanwhile, MIRDC provides IoT solutions tailored to production lines to facilitate smart manufacturing.
