Spraytek applies dip-spin finishes using several steps. After pre-treatment, we load the fasteners into baskets and submerge them into the coating. To remove excess material from the fasteners, we remove the baskets from the coating and spin them in alternate directions at high rotating speeds. Following the dip-spin process, we cure the fasteners in ovens to dry and develop hardness in the coating material.
Spraytek evaluates each order and part configuration to determine the best process controls and set up. We establish coating thickness by controlling paint viscosity, rpms and spin times. Multiple layers of paint may be repeated to meet different requirements. Our dip-spin process can apply organic and chrome-free finishes to automotive and non-automotive metal components. This highly efficient, cost-effective process provides high transfer efficiencies, high volume, short dwell times and oven-cured parts.
