PLASTIC MOULD & PRESS TOOL DESIGN

What is tool design?

It is a specialized area of manufacturing engineering which comprises the analysis, planning, design, construction and application of tools, methods and procedures necessary to increase manufacturing productivity.

Work holding tools – Jigs and Fixtures

A fixture is a work holding device and position the work; but doesn’t guide ‘locate or position the cutting tool’ the setting of the tool is done by machine adjustment and a setting blocker using slip gauges. A fixture is hold or clamp-end to the machine table. It is usually heavy in construction. Jigs are used on drilling, reaming, tapping and counter boring operations, while fixtures are used in connection with turning, milling, grinding, shaping, planning and boring operations. The use of jig and fixture makes possible more rapid and more accurate manufacturing at a reduction of cost.

Sheet metal dies

We’re specialized in the design and manufacture of dies for the cold-stamping of all types of sheet metal dies. Stamping presses and stamping dies are tools used to produce high volume sheet metal parts. The press provides the force to close the stamping dies where they shape and cut the sheet metal into finished parts.

 

Forging dies

Forging is a manufacturing process involving the shaping of metal using localized compressive forces.

Open die forging:-

Open die forging is also named free forging, means metal billets compressed under external compressive force and deformed to desired dimensions or shapes in a free way without forging dies.

Closed die forging:-

Closed die forging, also referred to impression die forging, is a process that heated by medium frequency induction heating furnace to high temperature and forged between upper and lower dies to get expected shapes like the drawing. Closed Die Forging is a forging process in which dies move towards each other and covers the work piece in whole or in part. The heated raw material, which is approximately the shape or size of the final forged part, is placed in the bottom die. The shape of the forging is incorporated in the top or bottom die as a negative image. Coming from above, the impact of the top die on the raw material forms it into the required forged form.

Extrusion dies
Extrusion dies can be made to form a virtually limitless array of shapes and sizes. The die itself is a steel disk with an opening, the size and shape of the intended cross-section of the final extruded product, cut through it.
Dies are broadly grouped as solid (or flat) dies, which produce solid shapes, and hollow dies, which produce hollow or semi hollow shapes. Combinations of solid, semi hollow, and/or hollow shapes may be incorporated into a single die.
A solid die may have one or more orifices or apertures through which the softened alloy is extruded. Multiple apertures in a single die produce multiple extrusions with each stroke of the press.
Semi hollow die extrudes a shape that is nearly hollow, partially enclosing a void, the area of the die tongue is large in comparison with the gap where the tongue is connected to the main body of the die.
Hollow dies take a variety of forms. Bridge, porthole, and spider dies, include a fixed stub mandrel as an integral part of the die. Each type of hollow extrusion die serves certain functions and carries its own advantages and disadvantages. The manufacturing methods and costs vary widely. The choice of design, and even manufacturing methods, will depend on the profile, press and container size, and production requirements.
Welding and inspection fixtures
We can design and build a manual or robotic welding fixture based on your needs. We can serve any industry — agricultural, recreational vehicle, furniture, or any industry requiring weld jigs. Our Design Engineers have designed hundreds of large and small weld fixtures.  Our team includes a range of talent, education and experience.  Giving you speed and accuracy in your weld fixture design.  From an Engineer with a Master’s Degree in Engineering and much experience in designing weld fixtures, to the high energy, high speed of a high-tech intern with a passion for all things mechanical.
Injection moulds
Injection moulding is one of the major processes for converting thermoplastics from pellet or powder form to useful products. The process involves heating the pellets or powder until it reaches the liquid state. The plastic is then forced into a cooled mould cavity, where it is held under pressure until the plastic returns to its solid state the process involves high pressures. Tooling is expensive and requires long lead time.
