The tool finishing section completes all tools produced, whether cast, laminated or both. Their work consists mainly of trimming, fitting, assembling and checking the entire tool for conformance to design specifications. Equipment required consists mainly of tool crib items, such as disk sanders, rotary files, and hand routers. All minor repairs and alterations to casts and laminates are made by this group. injection molders must be experienced, skilled tool engineers who know the entire plastics injection mold making operation and what is required of a tool in order that it function properly. They must be provided with work benches and adequate storage facilities for personal tools and equipment.
This section is used to test or “proof” the tool in either actual production equipment or simulated equipment. Such equipment as draw presses, stretch presses, hydropresses, etc. are often involved. Personnel should consist of tool and die makers with broad enough experience to enable them to alter a given tool so that it will function properly, and co-ordinate with other tooling involved. Service Facilities. In practically all plastics tool shops a central tool and supply crib is most economical. Such cribs must be stocked with adequate precision cubes, knees, straight edges, height gages, vernier scales and the accessory equipment normally needed in conjunction with these tools. A stock of hand tools, cutting tools, etc., required to do the actual work must be maintained. The same section will also store and dispense shop supplies. It is also a logical point to maintain inventory records of plastics materials, rein forcing material and all other major supply items required by the plastic moulding companies. Sanitary facilities must be provided. The most effective way to control industrial dermatitis is by practice of adequate personal hygiene. All personnel who come in contact with chemicals such as plaster, plastics resins, glass cloth, parting agents, etc., should be provided with individual steel lockers and adequate bathing facilities, including showers.
