Outsourcing outsourcing is not a new thing for the manufacturing industry. Enterprises choose outsourcing for many reasons, such as saving labor, space, and management costs. However, for most outsourcing companies without brand awareness, they do not have control over core technologies. In order to survive, they may cut corners to increase profit margins, and thus cut corners to reduce costs, And these issues are difficult for you, as a commissioned processing party, to monitor in place, so OEM brings many benefits while also burying potential risks for product quality. 

For contract manufacturing enterprises, their requirement for quality is to meet the quality needs of the client. But for the original factory, in order to create a brand that allows customers to trust sustainable development, it is necessary to always be prepared to iterate products in order to better and more accurately serve customers, in order to adapt to the ever-changing market. As a responsible enterprise for customers, a lot of work is required to complete everything from raw material screening, process flow, precision implementation, component matching and technical precipitation, to data collection and evaluation, and non-standard acceptance. And these are difficult to achieve in the OEM mode. 

The drawbacks of outsourcing 

OEM can often save more costs and achieve greater profits, but there are considerable risks involved, such as the processing of ceramics and silicon carbide barrels, which are the most common and important components of grinding equipment. However, ceramics and silicon carbide materials themselves have high hardness and brittleness, which brings great difficulties to processing and requires expensive diamonds and high-precision equipment for mechanical grinding. 

Moreover, the processing cost is high, the efficiency is low, and strong forces are generated during the grinding process, which can easily cause micro cracks or direct explosions on the surface, with a damage rate of about 10-20%. The price of a ceramic barrel or silicon carbide barrel in the market is very high. If there is a damage during the processing, it may be a month's worth of work. However, often outsourcing companies can only reduce the accuracy of the ceramic or silicon carbide barrel in order to obtain profits and avoid the risk of damage. The installation of low precision or microcracked ceramic or silicon carbide barrels on grinding equipment poses significant risks, which can easily lead to premature aging and unstable quality of the grinding equipment.   

Not only is it the processing of ceramic barrels or silicon carbide barrels, but the internal rotors, spindles, bearing seats, etc. are also the same. The accuracy is only a standard of a single thread, and this accuracy is directly related to the service life of bearings and rotors. Inaccurate concentricity results in ineffective synchronous transmission of components, and mutual wear, heat generation, abnormal noise, and aging of acceleration are also inevitable. Although there were no issues in the early testing, frequent adjustments to concentricity or replacement of accessories are required during production and use, which seriously affects the continuity of work.

   In terms of sealing for sand mills, it is somewhat cruel. Currently, over 80% of sand mill manufacturers in the market still use sealing technologies used in fields such as pumps and petrochemicals. If it were more than a decade ago, it would not have been a problem. However, with the improvement of grinding fineness in the market, the grinding medium has become finer, and this sealing technology can no longer meet the requirements for sand mills. The problems of leaking balls and materials are also piled up. 

Manufactured from the original factory, with free precision and "more stable" quality 

If a sand mill has 10 processes (which cannot be so few), and the qualification rates of the OEM processes are 95% respectively, what is the total qualification rate of this equipment? The answer is: 0.95 ^ 10=0.59, which means that the qualification rate of this sand mill is less than 60%, and the other 40% loss? Only customers can buy orders, so if you want to make a good sand grinder, you can only make it yourself.

   The production of Langling intelligent grinding equipment involves 10% global high-quality resource procurement of accessories, 90% self production or processing of accessories, with support from global grinding technology. It also has three major production bases in the country, including Dongguan Liaobu, which has dozens of CNC CNC machine tools and high-end processing equipment, fully achieving free control of accuracy. Langling Intelligent conducts secondary processing of important purchased accessories to achieve a perfect match with the original factory's production components. Taking ceramic and silicon carbide barrels as examples, to ensure the quality requirements of UM level and product stability, the processing time for a single barrel is usually around two to three days. Langling's 19 years of wet grinding technology precipitation, 90% of the accessories are produced or processed by themselves, which is a guarantee of quality and the processing strength of the enterprise.

   Which company is strong in sealing technology? In terms of making customers feel uneasy about "sealing", Langling strives to ensure that there is no leakage. The secret of this technology lies in the use of German sealing technology, utilizing the mechanical sealing principle of the front and rear end faces, relying on a cross-section perpendicular to the rotation axis, under the action of fluid pressure and compensation mechanism elasticity, as well as the coordination of auxiliary sealing, to maintain the relative sliding of the bonding and merging, truly achieving a seamless and impeccable sealing. The strong production capacity and business expansion ability have put forward higher requirements for quality control, To ensure sustained and healthy high-quality production and shipment, Langling uses processing equipment with an average replacement cycle of 3-5 years. With strong equipment investment, it ensures the fulfillment of its commitment to high quality. Such high investment is simply "unreasonable". Equipment matching is very important! As of now, the editor would like to focus more on the matching of equipment components, otherwise there is no way to explain why even with some excellent OEM companies, they still cannot assemble a good sand mill.

 As you all know, the vast majority of sand mills are non-standard equipment, and their components are customized according to the actual needs of customers. However, due to the personalization and complexity of the process design field, the process design theory is mostly guided by some guiding principles. Therefore, it is only a good wish to expect the OEM enterprise to make a stable and qualified sand mill according to the engineering drawings. The vast majority of OEM companies extract only the parameters of each part during production, and are unable to identify the true state of these parts in their work, as well as the related issues in collaborative operation with other parts. The biggest difference between non-standard equipment and standardized equipment is not the machines required for production, but the subjective use of human experience and skills in the long-term production process. It is a people-oriented and user-friendly operation, efficient process means, and the collection of long-term data statistics and experience information is completed through a summary with good openness and integration. Therefore, from another perspective, the core technology of Langling is the brand will of Langling people themselves.
