Zhongshan Oursun New Energy Co.,Ltd has a strict quality control system, from raw material purchasing to production and processing, to finished product inspection, each link is strictly controlled by professional staff. We understand the importance of quality, safety and environmental protection, and our products have passed a number of authoritative certifications, including ISO 9001 quality management system certification, ISO 45001 occupational health and safety management system certification and ISO 14001 environmental management system certification, etc. ISO 9001 ensures that our products, such as plastic battery cases, comply with the international quality standards, and ISO 45001 creates a safe and healthy working environment for our employees, guaranteeing our products from the source of production.ISO 9001 ensures that our products, such as plastic storage battery shells, meet international quality standards; ISO 45001 creates a safe and healthy working environment for our employees and guarantees the stability of product quality from the source; and ISO 14001 promotes the practice of environmental protection during the production process and reduces the impact on the environment.Meanwhile, our products have passed strict tests on mechanical, electrical, thermal and corrosion resistance properties to meet the stringent requirements of battery use.
The maintenance of automobile battery needs to be combined with its type of targeted maintenance: First of all, for the traditional lead-acid batteries, need to pay attention to the electrolyte level, if there is a reduction in the liquid phenomenon, should be supplemented in a timely manner with distilled water (can not be added to tap water or electrolyte), while regularly checking the junction stakes are corroded, can be coated with petroleum jelly rust; maintenance-free batteries do not need to replenish the liquid, but we need to pay attention to the appearance of the bulging, leakage, to ensure that the wiring is solid. Secondly, no matter what kind of battery, avoid long-term idling, it is recommended to start the car driving more than 20 minutes a week for its charging, long-term parking need to pull off the electrodes (first pull the negative pole, and then pull the positive pole). Finally, the daily use of the instrument panel to pay attention to the storage of electricity, insufficient to charge in time; if the power is insufficient on the way to the engine, can be a temporary power rescue, need to be connected to the positive and negative poles of the two batteries corresponding to the car.After the battery reaches the service life, when replacing the battery, you need to follow the principle of "remove the negative terminal first, then remove the positive terminal, and connect the positive terminal first, then connect the negative terminal when installing".
If customers find quality problems after receiving the products, they can contact our after-sales team within 7 days after receiving the goods, and provide product photos, problem description and other related information.We will respond within 24 hours and arrange technicians to verify the cause of the problem.If the problem is confirmed to be a product quality problem, we will provide return or replacement, rework and replenishment or other reasonable solutions according to the actual situation, to ensure that the customer's production will not be affected.At the same time, we will trace and analyze the problem and optimize the production process to avoid the recurrence of similar problems.
Yes, we can provide free samples.
Magic eye mainly uses PP (Polypropylene) and PC (Polycarbonate) to ensure impact resistance and stability. The core materials of the safety valve are PP (Polypropylene) and ABS (Engineering Plastic), which combine strength and chemical resistance.
We support customer customization. For example, if a customer needs a customized rubber cap valve, the customer should provide the following requirements: dimensions; valve opening and closing pressure values; raw materials; and hardness.
