Dies - Import export

Product ID: hob-02

In feed (Plunge) thread rolling dies: There are multiple starts (helix angle) at the edge of thread rolling dies. The type of thread rolling dies are sutiable to thread rolling of shorter length. the thread rolling progress as: Place a work piece in between of thread rolling dies, the screws are formed by strongly pressing progress, when the right thread rollign die returns, take out the work piece. (the work piece stays at the same rollng point). Thru feed thread rolling dies: The threads are as the rings on the surface of thread rolling dies. The type of thread rolling dies are sutiable to thread rolling longer length of screws. (longer then the length of thread rolling dies) The threading progress as: Set the helix angle with the roller shafts of thread rolling machines first, and insert the thread rolling dies. 1. Place a work piece in between of thread rolling dies, make sure the work piece is clamped by thread rolling dies. 2. The work piece is moving

For the mass production of fastener screws, it may also another good choice for the flat type thread rolling which may reduce production cost, applied to big-valume production. With the same named tool steel SKD11 (JIS) and SKH9, together with advanced heat treatment technology, and thread grinding CNC machien to offer the customer for another choice.

The knurling die: The knurling pattern with non-skid and attracting in appearance on manual tools (straight knurling pattern or diamond knurling pattern) by the knurling dies. The knurling pattern is formed by gear hobbing machine before the heat treatment process, the precision is less good as the grinding type, but, the straightness, and concertricity can be assured.

In respect of rolling the serration type working pieces as the transmission shafts of autobobile/motor-vehicles, spline shaft, and manual tools. The grinding type serration spline rolling dies can be ensured for the precision, delicate and smooth surface, extending the life of the rollers.

The superior tool steel is a very important element of thread rolling dies. SKD11 (JIS) and 1.2379 (DIN) are the named raw material which we have chosen for the past years. The blank of thread rollingd ies are heat treated by Japanese TECHNO vaccum & oil quenching furnace by heat treating dep. (TOYOGEN INDUSTRIAL CO.,) It will render the higher rigidity and higher wear-resistance of thread rolling dies. After the heat tratment progress, the thread rolling dies are ground by Swiss REISHAUER thread grinding machines. And another progress of tempering to reduce the grinding stress is necessary for thread rolling dies. The thread rolling dies are ready for sale after the quality exam. The good quality of thread rolling dies is able to offer higher precision, longer working life, and reduced the cost to customers. We also produce the thread rollingd ies for other brands thread rolling machines. Your special specifications and requirements are very welcomed.
