Quality control system and after-sales service guarantee
Ou Forging Heavy Industry Machinery implements the quality policy of "winning the market competition with science and technology, and winning the trust of users with superior quality".
The steel plate and round steel of the machine are purchased from well-known manufacturers, and the quality is guaranteed. It is not to purchase cheap and low-quality materials to save costs, so users can use it with complete confidence. Our company can make a commitment to you: if the fuselage and oil cylinder of our machine break during normal use within five years, our company will be responsible to the end.
The product quality assurance system and service quality assurance system of European forging heavy industry machinery are introduced as follows
1、 Product quality assurance system
1. Fuselage
(1) Use automatic wind cutting to cut the material, and then reverse the cut on both sides;
(2) During the assembly of the fuselage, the surface between the ribs must be flat without too large gap, which may cause poor welding;
(3) After assembly and spot welding, measure the form and position tolerance with a level ruler, angle ruler and ruler, and the tolerance standard is based on the unmarked form and position tolerance (GB_T1184 - 1996);
(4) The welding shall be started after the lapping is completed. The welding shall be carried out in sections and cooled by strong wind to avoid stress concentration. The welding shall comply with JB/T8609-1997 Technical Conditions for Weldments of Forging Machinery;
(5) After welding, the weld shall be polished and subject to vibration treatment, and then subject to aging treatment. The aging treatment time shall not be less than 20 days;
(6) After rough grinding of the surface, send it to the machining center;
2. Oil cylinder
(1) Material forging shall comply with JB/ZQ4000.7-86 General Technical Requirements for Forgings;
(2) Normalizing treatment shall comply with GB/T16923-1997 Specification for Normalizing and Annealing of Steel
(3) The inspection of lathe after machining shall be in accordance with GB1800-1804-79 Tolerance and Fit Standard, GB1182-1184-80 Shape and Position Tolerance Standard and GB1031-83 Surface Roughness Standard;
(4) The surface of plunger rod is plated with hard chrome GB11379-89 Metallic Coatings - Chromium Electroplated Coatings for Engineering;
3. Hydraulic system
(1) The cartridge valve shall be of well-known brand, and the quality shall be strictly controlled;
(2) After the motor and oil pump are connected, test run, and use a dial indicator to check that the run-out rate is not more than 0.3 mm;
(3) Leakage test shall be conducted after the tank is welded;
(4) The welding of pressure pipes adopts GB50184 Standard for Quality Inspection of Industrial Metallic Piping Engineering;
(5) The pressure of high-pressure hose shall not be less than 60MPa;
(6) The hydraulic system shall be cleaned twice before starting.
2、 Service quality assurance system
Ou Forging Heavy Industry Machinery has many service outlets in the country, such as Zhuji, Taizhou, Wuxi, Jining, Shenzhen, etc. In the context of increasingly wide product sales, our company will also add more service personnel and sales outlets. The company will conduct a monthly network meeting for after-sales service personnel to investigate the after-sales service situation of the month in order to obtain product quality feedback, and can improve the deficiencies in time.
Active service: 80% of the faults of the hydraulic system come from the cleanliness of the oil. Our company will clean the hydraulic system and replace the filter element for free once for the equipment within three years. For each equipment delivered from the factory, our company will not only send people to install and debug, but also assist users to trial-produce products and train operators.
The establishment of a complete service system is the core of the marketing strategy of the European Forging Heavy Machinery Co., Ltd., and the constant improvement of service efficiency and quality, and the true realization of "customer first and customer satisfaction" are the consistent requirements of the European Forging Heavy Machinery Co., Ltd. for all employees.
Service and support
Service purpose
Ou Forging Heavy Industry Machinery always puts quality and service at an important position and sales at the second place. It drives sales with professional products and high-quality services.
professional services
Preventive on-site maintenance service sends personnel to carry out preventive on-site maintenance once a quarter to check the potential failure of equipment operation and eliminate it in time without affecting the production of users.
On-site location service
Provide users with the whole process of shipment from the manufacturer to the customer to ensure the arrival of the equipment and reduce the risk of damage to the equipment during transportation.
Delivery reminder service
Before the equipment leaves the factory, the specialist shall notify the customer of the expected arrival time of the goods, the lifting tools to be prepared and the supporting facilities required for the equipment.
Installation and commissioning services
Our company sends people to install and debug each equipment. During the installation process, we strengthen the communication with the customer's operators, and adopt the registration system. For example, installer A goes to customer A for installation. If customer A's equipment fails this year, we can directly contact installer A for consultation, because installer A is familiar with the customer as well as the customer's site.
Annual maintenance plan
The hydraulic system needs to be cleaned regularly to filter the dirt of the oil. Our company provides annual maintenance service for each user (free of charge within two years). The customer does not need to find another person to maintain the equipment, because our company will remind the customer on time, so that the customer can really enjoy the ease of purchase and use.
Service repair response time
On-site service within 24 hours (Zhejiang Province)
On-site service within 48 hours (Jiangsu, Guangdong, Fujian, Jiangxi, Anhui, Shanghai, Shandong)
On-site service within 72 hours (other provinces)
