ã€China Aluminum Industry Network】 1. People are streamlined and “thin†type management companies in Hong Kong are generally small and medium-sized enterprises. There are fewer employees than 100, and most of them are between 20 and 50 people. According to Luo Baihui, deputy secretary-general of the Shenzhen Mould Technology Society, the configuration of various types of personnel in Hong Kong-owned mold and die enterprises is very streamlined. The ideas of lean production and "lean" management have been well reflected.
The production organization of Hong Kong mould enterprises is generally of high efficiency. When the quotation and the production cycle are expected, the main structural scheme has been basically determined. A preliminary design scheme will soon be available, and the standard formwork models and various types of production materials, specifications, etc. will be formulated. Size and other information. After the contract is signed, the model number of the standard formwork and various specifications of the material to be purchased shall be transmitted to the supplier by fax, and the material size data of the blanking and roughing can be arranged on the shop floor immediately to the workshop, according to the production of the workshop. Design work to ensure the continuous production of the workshop, corresponding organization and coordination of the design work, basically break the traditional mode of design after the first processing. We pay great attention to the high-tech molds with complicated technology, and we design with care and design quality. Flexible deployment of design and production generally does not delay work schedules.
The workshop production is strictly processed according to the drawings, and technicians of different technical levels arrange the corresponding parts drawing processing. Generally, the quality and progress of each set of dies are handled by a technician; the workshop supervisor is responsible for production scheduling, organization and coordination, and is responsible for the overall quality and progress; The management personnel are generally technically rigorous and dare to be responsible. The relationship between management responsibilities, rights, and profits is more simplistic and clear. Production arrangements, coordination and major technical problems have arisen. The management is responsible for the main responsibilities; The problem is who will be responsible for the operation, and the boss is mainly responsible for the overall operation of the factory.
The skills of mold technicians are generally more comprehensive, including cars, milling, grinding, pliers, and sparks. Milling machine processing technology is dominant, and milling cutters are mainly based on grinding all kinds of forming cutter technology. Technicians with higher technical level can grind all kinds of R milling cutters, spherical milling cutters, T-shaped milling cutters and different specifications of milling cutters , As small as φ0.6mm×3.0～4.0mm milling cutter with 0.5°～1.0° inclination, and open double edge. The master milling machine of engraving machine is its main technical force. Hong Kong masters have spent considerable time on sharpening techniques and have developed higher skills. The Hong Kong-owned mold factory also pays more attention to the development of fitter technology. For example, the highly transparent plastic mold has high requirements for the polishing technology. The polishing technology determines the quality of such molds. Polishing fitters must be skilled in the use of electric and pneumatic tools and strictly implement various polishing process routes. Most of the polishing processes rely on manual operations, so most mold companies pay attention to the development of specialized polishing mechanics. The deep research on the characteristics of various materials and polishing process has a great influence on the improvement of mold processing technology and quality.
2. Professional process, accurate positioning Hong Kong mold enterprises generally have relatively stable customers, and the proportion of individual customers is small. Most of the customers have delivered molds for the whole set of products. The customer has discussed with the owner of the mold factory and the general manager about the number of sets of molds to be produced and the number of pieces issued by each mold, and put forward the necessary technical requirements. The owner of the factory and the technical supervisor agree on the design plan of the mould, the budget cost and the production cycle according to the requirements, and report it to the customer after verification. The main content of the contract is generally price, delivery date, mold materials and special technical requirements. The payment method has basically been established. After the contract is signed, 40% of the price will be paid as the deposit. After the trial, the payment will be 30%. After delivery, the remaining 30% will be paid.
Many mold companies are mostly focused on the needs of various types of molds in the automotive, electronics and other industries, and determine their own product positioning and market positioning. In order to survive and develop in the market competition, each mold manufacturer has its own superior technologies and products and adopts specialized production methods. Most Hong Kong mold companies have a long-term cooperation with mold users, and there are also a number of mold production cooperative manufacturers around large mold companies. This reciprocal, mutually beneficial, win-win, and coexistence partnership has continued for 30 to 40 years.
3, information technology, management integration Hong Kong's mold enterprise production equipment in the 80's are mostly machined EDM and wire cutting and other conventional equipment, equipment and more with electronic ruler and other digital display device, milling machine used in Taiwan can be along two sides Rotary head vertical milling machine, milling machine with electronic ruler digital display (x, y-axis digital display). The processing method is coordinate data processing, the workpiece processing is fast and accurate, and the fitter is rarely used for fitting. The machining method of the milling machine is the same as the principle of numerical control milling. With some fixtures, the 2.5D quadratic surface can be processed. According to the processing technology, the dimensional standards of the drawings shall be marked by coordinate method. The contents of the drawings include structural design, various processing methods and processes.
In the 1990s, Hong Kong mold companies began to invest in CAD/CAM hardware and software equipment, especially large-scale mold companies, which basically achieved computer management. The technological progress of mold factories mainly depends on the improvement of CAD/CAM technology.
At present, the manufacturing level of Hong Kong-owned mold enterprises has reached a new level. Larger mold companies have more than 10 machining centers and CNC milling machines, and established a computer network. The application of CAD/CAM technology has become more popular, and engineering and technical personnel are more familiar with CAD/CAM technology. From the production planning, process development, to quality inspection, inventory, statistics, etc., computers are commonly used. Various departments within the company can share information through computer networks.
