With project-based R & D as the core, the company has established a scientific and reasonable R & D process. On the basis of collecting and sorting market demand information and technology development information, the company carries out new product and application development. After feasibility demonstration, the company enters the links of project approval, review, design, trial production and acceptance, and completes the product R & D process.
2. Procurement mode: the materials purchased by the company are mainly the raw materials and auxiliary materials used for the production of lithium-ion battery diaphragm. The raw materials are polypropylene (PP), polyethylene (PE) and additives, and the auxiliary materials are general raw materials such as packaging materials and production auxiliary materials. The company forecasts according to actual orders and historical data, negotiates with suppliers and distributors and issues purchase orders. The company has established relatively perfect supplier selection and evaluation control procedures to select suppliers, manage qualified suppliers listed in the list of qualified suppliers, and conduct strict supply assessment and regular evaluation on qualified suppliers.
3. Production mode: the company basically implements the order production mode of “production based on sales”, formulates the ISO production process control procedure, and establishes a set of processes for quickly and effectively processing customer orders. After signing the order with the customer, the company carries out the production organization management of the whole process of production planning, procurement organization, production and storage, quality control, shipment and so on according to the product technical indicators, specifications, quantity, delivery date and other order contents required by the user. The production mode is conducive to meet the requirements of different customers, improve the on-time delivery rate of orders and customer satisfaction, improve the consistency of product quality and reduce the inventory level, so as to reasonably control the cost and improve the efficiency of capital utilization. In addition, in order to make full use of the company’s production capacity, the company also prepares goods normally according to the previous product sales history and in combination with the specific needs of customers.
4. Sales mode: the company mainly adopts the direct sales mode of direct sales to end customers, which is sold in both Chinese and foreign markets. It mainly obtains orders through Internet publicity, door-to-door negotiation with target customers, participating in customer bidding, participating in industry exhibitions, etc. Due to the complex material system of lithium-ion battery, the manufacturing process requires high-precision control. Diaphragm suppliers are required to provide supporting technical solutions under different material systems and control systems and professional and timely technical support and services before, during and after sales, so as to ensure the excellent quality of lithium-ion battery products.
