The Chinese market has been in line with international standards for many years. With the increasing number of foreign products “flying into the homes of ordinary people,†people have gradually gained a better understanding of the quality of foreign products, but many people still have There is a sense that "good foreign goods must be better than domestic goods." For example, the Household Appliances Association of Jiangsu Province disclosed that the quality of foreign mobile phone quality complaints is three times that of domestic mobile phones. Although there are multiple reasons, it is also a wake-up call to people. However, the sales of foreign brand mobile phones have always been very prosperous, but the story behind the estimate is also worthy of people to explore.
Coincidentally, on the lube oil products that are familiar to the auto race, a series of incidents of foreign oil entering the ground caused serious concern in August. First, the Jinan Entry-Exit Inspection and Quarantine Bureau found that the low-temperature dynamic viscosity and pour point of imported US vehicle lubricants were not in conformity with the “Gasoline Engine Oil†(GB11121-2006) standard requirements, and the Bureau had degraded its success. Then on the 11th, the Dongguan Inspection and Quarantine Bureau sent personnel to supervise the destruction of a batch of imported unqualified gasoline engine oil produced in the United States, totaling 27 boxes and 108 bottles. The batch of motor oil was sampled and tested, and the results showed that its pour point did not meet the mandatory requirements of GB11121-2006 “Gasoline Engine Oilâ€. The inspection and quarantine bureau carried out sealed disposal of relevant goods in time according to relevant regulations. The batch of unqualified engine oil was transported to a professional lubricant. Recycling agencies destroy the site. Finally, under the supervision of the Huangdao Inspection and Quarantine Bureau, a total of 70 cartons of unqualified imported vehicle lubricants from South Korea were directly shipped out of the country. The inspection found that the high temperature and high shear viscosity of the goods did not meet the mandatory technical requirements of the national standards.
In addition to these exposures, similar incidents without exposure should also exist. First of all, we must thank the inspection and quarantine bureaus at all levels for their due diligence and protect the interests of consumers. At the same time, the relevant inspection and quarantine departments also recommend that consumers should rationally and reasonably select vehicle lubricants, not blindly superstitious about foreign brands.
As cars enter the lives of ordinary people, the matching of lubricant products cannot be ignored. If you use a product with unqualified quality, it will definitely cause damage to the engine and cause the owner to suffer serious economic losses. If you know that it is because of improper selection, there is a problem with the quality of the lubricant and you will regret it. Because of its importance to vehicle protection, automotive lubricants must choose high quality products. The above example shows that foreign brands may not always be reliable. Then, what is the quality of the Chinese lubricants market? There are many brands in the Chinese lubricants market, and some small factories produce low-quality products for economic interests or the quality of the products is unstable. However, the products of the regular manufacturers are still Can be trusted. In fact, China's lubricants manufacturing standards have been in line with international standards, and the adopted oil standards have been synchronized with the world. The individual formulas will be slightly adjusted, but it will not affect the quality of the entire product. Choosing an ideal lubricant should not be only concerned with its origin, but should be the quality level and viscosity level of the lubricant. In this regard, regardless of where the origin is, quality standards are internationally accepted. The lubricant oil manufacturers in China have tailor-made automotive lubricants for China's road environment, I am afraid it is more suitable for local consumers.
From the materials disclosed by the inspection and quarantine bureaus across the country, the products of China Lubricant Manufacturers rarely enter the unqualified list during inspections. This is a phenomenon that we are pleased with and is also a guide for consumers to purchase oil products. Take Changcheng Lubricating Oil, which is well-known to everyone, as an example, it has basically remained undefeated in hundreds of sampling inspections conducted by quality supervision departments at all levels of the country. Under its large quality system, Great Wall Lubricants extends from product quality to service quality and establishes a full-scale, comprehensive quality management and control model for product design, raw material procurement, manufacturing and manufacturing, product storage and transportation, product sales, and service, to meet and satisfy Standard requirements, strive to exceed user expectations. Great Wall Lubricants has successively cooperated with more than 90% of Chinese foreign, joint venture, and autonomous car companies. Obviously, lubricants can already be selected from Chinese brands to trust a good product. In the major auto forums of the Internet, a group of wholesalers often discuss, and which "made in China" can match and surpass foreign products, they can be described as "smart people" and "smart people" among consumers.
Whether it is a lubricant or other products, whether it is foreign brands or "made in China," high-quality good products are what consumers really need, and they have to go out of the thinking that "foreign brands must have good quality", comb their own needs, and look at Chinese and foreign customers. The value of brands and products, the purchase of products that make them comfortable, and the choice of quality not to choose a nationality, this is a good choice. This choice will not only achieve its own satisfactory results, but also guide and promote Chinese and foreign manufacturing companies to pay more attention to the forging of high-quality products, thereby creating a more favorable consumer environment.
Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term "lost-wax casting" can also refer to modern investment casting processes.
Today, more advanced waxes, refractory materials and specialist alloys are typically used for making patterns. Investment casting is valued for its ability to produce components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys.
The fragile wax patterns must withstand forces encountered during the mold making. Much of the wax used in investment casting can be reclaimed and reused. Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process.
Investment casting derives its name from the pattern being invested (surrounded) with a refractory material. Many materials are suitable for investment casting; examples are stainless steel alloys, brass, aluminium, carbon steel and glass. The material is poured into a cavity in a refractory material that is an exact duplicate of the desired part. Due to the hardness of refractory materials used, investment casting can produce products with exceptional surface qualities, which can reduce the need for secondary machine processes.
The process can be used for both small castings of a few ounces and large castings weighing several hundred pounds. It can be more expensive than Die Casting or Sand Casting, but per-unit costs decrease with large volumes. Investment casting can produce complicated shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional surface qualities and low tolerances with minimal surface finishing or machining required.
We can supply big range of such investment Casting Parts.
