Fang Punches & Products

Custom Manufacture

In addition to our standard parts, the TD Coating Centre can also manufacture custom made parts. These can either be modifications to existing standard parts or as per your required spec. All that is required is to provide us with a drawing and a description of the operation and/or problems experienced.
We will engineer the part where necessary in order to offer you a cost effective solution. Email us a drawing to technical@td.co.za

Speciality Steels

The TD Coating Centre can manufacture parts from a full range of hot and cold work steels, high speed steels, Powder Metallurgical High Speed Steels. Matching the correct steel and coating with the application not only ensures durability but can offer the best overall economy and means we can accommodate applications from mild to wild.

Tungsten Carbide

In order to offer complete wear solutions, the TD Coating Centre can also manufacture from cemented carbide (aka “tungsten carbide). Solid carbide tooling offers the highest base hardness throughout the tool and as such is an excellent base for thin film coatings. Tungsten carbides with a cobalt binder content of over 10% can be TD coated, whilst all tungsten carbides can be PVD coated with TiN or TiAlN for further wear resistance.

Punches
The range of developed punches and dies are made to international standards and with world class steels.
Base materials that are more compatible with certain coatings are used rather than traditional materials, however these steels are still tough, chip resistant and of high strength to handle punch stresses.

The NANO coated punches are highly resistant to pick-up and adhesion. The NANO-punches can be used on conventional mild steels, difficult steels such as stainless steels, and other non-ferrous materials such as copper and aluminium. The NANO coating lends itself to high precision parts and hence even thin plastics and foils can be punched.



The TD coated punches are very high performance parts, with the TD coating being highly resistant to pick-up and wear. Conventional work materials and difficult-to-work materials can be easily and cleanly punched and increases in life of up 20 times have been found. The punches are very resistant to edge chipping and breakage, and are a very cost effective, high performance solution.

Both the TD and NANO coating are exceptionally hard (90 HRC), but very tough and can take severe punishment. The coated punches can also be sharpened and re-used. The high bonding strength of the coatings ensures it remains on the sharp cutting edge without peeling, while the flank wear resistance is maintained.

Uncoated Punches
Uncoated punches can be supplied. These precision-made items are tough yet durable and comparable with international class items, for short to medium production runs.

Custom Made Punches
Standard punches can be modified to suit customer’s requirements. Please supply us with a drawing via email, or fax +27-(0)11-9085396. We can supply one off to 1000’s of parts.


FANG Pilot Punches
Pilot punches are made from high strength cold work steel, and TD coated to ensure extreme resistance to wear, pick-up and sticking. Parts slide and locate easily on the pilots. Critical dimensions of the pilot are also maintained for longer which assists in producing consistent parts.


FANG Dies
The FANG range of dies are long lasting parts where the sharp cutting edge assists the punch in piercing a hole. The dies can be re-sharpened as the coating will still preserve the sharp cutting edge and reduce drag.
The short land dies mean a standard punch stroke to clear the slug, whilst getting good life from the die. Standards are made to ISO 8977, or as specified.


Locating Pins
Locating pins are used for accurately placing and locating parts. Our coated parts are very resistant to wear, scoring and loss of dimensions on the pins. Very resistant to the aggressive wearing action of burrs on pre-pierced holes. Where consistent accuracy is required, such as in high precision welding operations, our range of locating pins should be used.


Burring Punches
The FANG burring punches maintain the sharpness of the piercing tip, while coatings ensure the part is highly resistant to pick-up and scoring on the forming edge.

Extrusion Punches
TD coated parts have very high resistance to pick-up, scoring and wear. Parts show a very smooth extrusion surface ideal for tapping threads or for sealing purposes.

Ejector pins/Knockout Pins
Our ejector pins are made from hot work tool steel for hot applications. Pins are Diffox, NANO or ARMOLOY coated for a smooth, anti-stick sliding surface with high corrosion resistance.
Similar to ejector pins, these parts are used in cold to warm applications (~400 °C). With a higher base metal hardness of 58 – 60 HRc, the pins can take high stress without deforming. Pins are either TD coated for extreme resistance to wear and pick-up, or NANO coated to ensure smooth sliding and long life.



With the coatings, the parts also prevents wear on the opposing hole.

Core Pins
Our core pins feature a very smooth, anti-stick surface to facilitate easily removal of the product from the part. Cores holes are smooth and sticking is virtually eliminated. High finish can be specified and maintained throughout the production cycle with the help of coating.

Plain Pillar and Bush Sets
Our pillars are Armoloy coated to ensure a smooth, low friction surface which is highly resistant to adhesion and scoring. The bushes are DIFFOX coated to ensure a mating surface with very low resistance to sliding. Minimal lubrication is required for these parts to work optimally.
