Latest Patents
Krigbaum holds a patent for an "Amino molding compound for cold manifold injection molding." This invention involves a urea-formaldehyde corn that is mixed with added paraformaldehyde and urea, along with a catalyst system and other conventional additives. The resulting mixture is a fine powder that can be densified and granulated. The unique formulation allows for low viscosity under cold manifold injection conditions, making it particularly suitable for cold manifold molding applications. The patent emphasizes maintaining low condensation of resin during drying by using high formaldehyde to urea ratios and specific pH values. Additionally, the plastic life of the molding compound is enhanced through the use of a catalyst system, such as zinc sulfate and hexamethylenetetramine. The compound remains stable at temperatures between 82°C and 110°C for over five minutes and can be injected at pressures below 125 megapascals (18,000 psi) without setting in the sprue or runners.
