DESIGN DEPARTMENT in Tool Design Engineering
Tool design is a specialized area of manufacturing engineering which comprises the analysis, planning, design, construction and application of tools, methods and procedure necessary to increase manufacturing productivity.
To carry out these responsibilities, tool designer must have a working knowledge of machine shop practices, tool making procedure, machine tool design, manufacturing procedures and methods, as well as the more conventional engineering discipline of planning, designing, engineering graphics and drawing, and cost analysis.
RESPONSIBILITIES OF TOOL DESIGNERS:
Tool designers are responsible for a wide variety of special tools. Whether these tools are an end product or merely an aid to manufacturing, the tool designer must be familiar with the following:
Cutting tools, tool holder, cutting fluids, Machine tools, Jigs and fixture, Gauges and measuring instruments, Dies for sheet metal cutting and forming, Dies for forging, upsetting, cold finishing and extrusion, Fixtures and accessories for welding, riveting other mechanical testing.
It is the main organ of the industry. Quality of work done and hence the name & fame of the company depends largely on this section. Its functions can be enlisted as below.
• Collection of required technical data, study of component drawing etc.
• Design calculations are done and suitable assumptions are made.
• Design layout by considering cost effectiveness, machines available. It also includes Comparing new design with similar.
• Design review, design verification and changes if any will be implemented.
• Preparation of drawing and bill of materials.
OBJECTIVES OF TOOL DESIGN:
The main objective of tool design is to increase production while maintaining quality lowering costs
Therefore the tool designer must realize the following objectives:
• Reduce the overall cost of manufacturing a product by producing acceptable parts at the lower cost.
• Increase the production rate by designing tools that will produce parts and quickly possible.
• Maintain quality by designing tools, which will consistently produce parts with the required precision.
• Reduce the cost of special tooling by making every design as cost effective and efficient as possible.
• Design tool that will be safe and easy to operate.

CHECK POINTS IN MOLDING TOOL:
- Mold halves fit only in one position.
- Guide pins must be longer than highest part of the mold insert.
- Horizontal matching faces at correct level.
- Cavities polished in opening direction.
- Surface finish/ polishing of cavity & core inserts.
- Perfect matching of pins & inserts.
- Are there sufficient ejector pins.
- Ejector plates guided properly.
- Sprue bush radius, taper & also finish of sprue taper.
- Are hardened inserts/plates provided in back plate to avoid digging by
- Cooling water connection flow & leakage.
- Is there sufficient clearance between CAM and slide in closed position?
- Are the guide pins longer than the CAM pins, so that they engage first?
- Is the slide support hardened?
- Gate and positions
- STEPS IN DESIGN:
- Gathering data’s and establishing design objectives.
- Design proposals: Two or three alternate proposal may be discussed in detail before arriving at the final proposal.
- Approval of concept design: This should be finalized with all concerned - customer, the tool room personnel and the production personnel.
