Chi Ning Cold heading machines
Automatic presses made by Chi Ning (Taiwan) using advanced technologies which are utilized by the leading American and European industrial companies. Because Taiwan companies offer their products by low prices (due to their lowlabor costs), equipment produced by them is more attractive for the Russian companies with lower budgets.
Cold Forming Production is Profitable
Automated cold heading presses are widely used in a modern industry for production of screws, bolts, nuts (including special items), bushings, rollers, cartridges, etc., by a cold heading method. These presses have the following features:
- High production rate (up to 350pcs/min for Chi Ning – F11B)
- Low products cost
- Labor output ratio is several times less compared with traditional machining methods using metal cutting equipment
- Practically wasteless technology: material utilization factor up to 0,90-0,97
- Easy equipment readjustment for changing from one part type to another
- Economically sound minimum lot size of run-out production from 25 to 50,000 pieces (with equipment fully work loaded with production of similar parts)
Wide Range of Models
Wide-range of offered automatic presses allows to select the appropriate equipment in an optimum way keeping in mind their application and dimensions of the produced parts.
For comprehensive solutions of client needs at delivery of their equipment manufacturers offer additional tooling. Thus, the company Biing Feng can deliver by customer’s order a cold heading tooling: dies and punches, solid and combined hard alloy inserts for combined matrixes, cutting bushings, etc. The company Chi Ning specializing in a manufacture of automatic presses for production of various bolts and screws offers also nut-tapping machines.
