Wilco Molding, Inc offers multiple secondary services to enhance the value of our customers’ parts.

Sonic Welding - Ultrasonic welding is an industrial technique using high-frequency ultrasonic acoustic vibrations that are locally applied to the parts being held together under pressure to create a solid-state weld. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together.

Solvent Welding - Solvent welding is when a solvent is applied which can temporarily dissolve the polymer at room temperature. When this occurs, the polymer chains are free to move in the liquid and can mingle with other similarly dissolved chains in the other component. Given sufficient time, the solvent will permeate through the polymer and out into the environment, so that the chains lose their mobility. This leaves a solid mass of entangled polymer chains which constitutes a solvent weld.

Heat Staking - Heat staking uses heat to deform the plastic boss, instead of cold forming. A plastic stud protruding from one component fits into a hole in the second component. The stud is then deformed through the softening of the plastic to form a head which mechanically locks the two components together. It is a versatile technique benefiting from being quick, economical and consistent.

Heat Transfer Labeling – Almost acting like an iron-on, the ink from the label is transferred directly onto the part creating a very clean, high-end decoration on the part.

Hot Stamping - In the hot stamping process, a heated die applies pressure to a hot stamping foil that is pressed against the plastic part. The heat and pressure from the die transfers the pigment from the hot stamping foil onto the plastic part.
