Hyde Industrial Blade Solutions (IBS), a division of Hyde Tools, Inc., today announced the acquisition of two manufacturing firms to bolster the company’s offerings in the plastics and tire and rubber marketplaces. D&S Manufacturing and PDK Design & Grinding, both of Auburn, MA, will become part of the Hyde Group of companies. D&S Manufacturing has specialized in the manufacturing of high-chrome alloy tool steel granulator and shredder and recycling knives used to break down plastic material for more than 70 years. For over 85 years, PDK Design & Grinding has been a leader in the manufacturing of tungsten carbide rotor knives and bed knives for pelletizing plastic before being converted to a final product. Both firms also offer grinding services for the re-sharpening of their respective knives and blades. According to Hyde, there will be no immediate or outwardly apparent changes for D&S and PDK customers. Sales, service support, ordering and engineering contacts will remain the same at both companies.
