Hualing Heavy Auto, covers an area of 80,000 square meters,has advanced heavy auto product line and annual production of 20,000 heavy auto. Hualing Heavy Auto realized ERP (Enterprise Resource Planning) information management. All its punching, welding, painting and assembly equipments and test equipments are imported from Japan, German, France and Australia.
Frame punching line is composed of 5 punching machines. The 5000 tons longeron punching machine is imported from Japan Kawasaki ensure that girders are punch molded at a signal time and realize automatism of feeding, molding and laying off.
Body punching lines, consisting of 10 units more than 800t-punching machines, have A and B punching lines. All punching machines are controlled by PLC.
Moulds introduced from Japanese and Taiwan: technological mould equipments are crucial for standardized and modernized production with high quality, for construction of heavy-duty trucks with international quality. Therefore, to realize standardized and moulded production, our company has introduced more than 630 moulds for cabs, 102 moulds for car frames (13 moulds for girders, while 89 for crossbeams) from Japanese and Taiwan.
13 welding robots introduced from Japan constitute a fully automatic production line. Robots grasp work pieces to carry out welding so as to ensure precision and quality of cab welding. Welding equipments are composed of 22 riveting machines, 103 sets of electric-controlled tolls, 76 suspension shot welders and auxiliary facilities and equipments. All welding operations are realized by robots, which is unique among domestic truck manufactories and unmatched by some sedan manufactories. With adoption of imported clamps and checking gauges, with welding parameters and quality supervised by computer system, steady and reliable welding quality of domestically produced cab assembly is ensured.
Paint workshop, an enclosed modernized shop with mechanical ventilation, is one for heavy-duty trucks with the most sophisticated equipments, rather high automatically, relatively advanced techniques and the most scientific management to the extent of present domestic level. The globally latest copy spray painting technology is adopted in painting, AUDIT management mode is applied in quality control, and central monitoring system is used to execute real-time monitoring to the entire paint shop and to conduct whole-course tracing and monitoring to work pieces entering the production line. To ensure painting effect of the overall car body, prime paint of car body and car frame is applied by virtue of cathode electrophoretic manufacturing technique, while finish paint is applied by French Sames automatic spray coater.
Coating line for car frame: work pieces are conveyed by underslung conveyer with program-controlled rail, program-controlled overhead crane and ground sled conveyer etc. For preliminary treatment, “moderate temperature” phosphatization is applied to desludge and deoil, and for prime paint, advanced cathode electrophoretic technique is employed.
Coating line for car body: car body of finished processing chamber is provided with special coatings such as anti-stone-bumping coating, sealant for welding seams, heat resisting and shockproof damping fin, chamber wax etc. Finish paint is applied by French Sames automatic spray coater, with paint and sealants conveyed by American Craco equipments.
Assembly workshop, with rather high mechanization degree, is primarily divided into 7 regions -- main assembly line, trim line, pre-assembly line for car frame, pre-assembly line for the engine, pre-assembly line for odds and ends, rework line and storage lines. Automobile assembly technique from Japanese Mitsubishi is applied in final assembly. Assembly line for chassis is equipped with central control room, fault diagnosis system and information feedback system. Detection is performed by comprehensive electric detector and detection line of the entire car so as to ensure assembly quality.
Console of assembly shop: advanced electronic monitoring system is used to effectively ensure safe, ordered, smooth and highly efficient production work in the entire shop.
Trim line of assembly shop: assembly line in the cab, an automatized one with a length of 120m, is equipped with 5 sets of booster mechanical hands which are used to assemble instrument panel, seats for pilot and second pilot, wind shield, to dismantle truck door respectively.
Assembly line: pre-assembly of the engine pre-assembly line for engines in flow production
Final assembly line in assembly shop: final assembly line, a modernized assembly line, is equipped with advanced equipments such as bolt tightening machine, KBK, tyre lifting platform, vacuum filler, gathering and exhausting system for tail gas etc. With an annual production capacity of 15000 vehicles, this assembly line is the most advanced internally.
Assembly shop: test line By virtue of advanced fault diagnosis system and automatic detecting system, assembly condition and quality condition can be detected rapidly and thoroughly, thus ensuring assembly quality of the entire truck.
Xingma Automobile is one of the biggest special purpose vehicle production bases in China. It has several series products.
