MOLDERS OF APPLIANCE HOUSINGS AND COMPONENTS MAY REALIZE SIGNIFICANT COST SAVINGS AND IMPROVE MOLDING PLANT EFFICIENCIES THROUGH SELF-COLORING OF THERMOPLASTIC RESINS. BY MIXING COLOR CONCENTRATES AS NEEDED WITH UNPIGMENTED RESIN INSTEAD OF USING PRECOLORED RESINS, MATERIAL COSTS ARE REDUCED AND RESIN INVENTORIES CAN BE CONSOLIDATED. CAPITAL EXPENDITURES ALSO MAY BE REDUCED, ALLOWING FOR A MORE FAVORABLE, LONG TERM, CASH FLOW POSITION. MOLDING OPERATIONS ALSO CAN BE OPTIMIZED THROUGH IMPROVED EFFICIENCY OF EQUIPMENT AND SPACE. THE MANUFACTURING IMPROVEMENTS IN CONSISTENCY AND QUALITY OF PLASTIC RAW MATERIALS AND IN AUXILIARY EQUIPMENT FOR MOLDERS HAVE BEEN IMPORTANT FACTORS IN THE CONTINUED MOVEMENT TOWARD SELF-COLORING.
