YH Precision: The digitalization of "World Factory" is not "tall and tall"

YH Precision, located in Chang'an Town, Dongguan, is a manufacturing enterprise specialized in producing plug parts in data lines ——They design molds, purchase raw materials, produce assembly parts, and make good conversion plugs, which are the key parts for making Type-C data lines commonly used in our lives.

“ In recent years, it is not easy for a production factory like ours to survive 。 In terms of cost, the cost of rent, manpower and raw materials kept rising; In terms of revenue, orders generally decreased. It's getting harder and harder to do business. In fact, we are lucky. " Hua Jiansheng, Deputy General Manager of YH Precision.

How to understand what Vice President Hua said about "luck"? Without field visits, it is hard for us to imagine that such a small family of local factories can achieve an annual revenue of more than 30 million yuan and an output increase of 80% year on year, Go global in the fierce industrial competition and win the connector production orders for Sony, Nintendo, Xiaomi and other first-line terminal electronics brands 。

In the story of YH, we saw the tenacious vitality of small and medium-sized manufacturing factories, and the value of digital transformation behind the wisdom of increasing income and reducing expenditure.

But for many small and medium-sized enterprises, the first step towards digitalization is to improve real and complicated links 。

For example, if a factory wants to successfully obtain an order, it must first pass the ISO9001 quality management system certification. For the manufacturing industry, this certification is not only a certificate, but also an entry ticket to receive orders. Especially for medium and high-end projects and transnational projects, ISO certification will be taken as the access condition to ensure product quality.

It is not easy to get this certification. Not only does it have strict requirements on the management level of the factory, but also to ensure the continuous validity of the certificate, complex qualification materials must be submitted every three years, reviewed again, and recertified. This is an unavoidable trouble for many traditional manufacturing factories.

With one of them“ Production quality control process record ”For example, the factory needs to submit all quality inspection records for three years, that is, how many good products and how many different products are in each production line every day. Previously, this information was recorded on paper. One production line had to be inspected every two hours. There were 12 records in one day and 13140 records in three years 。

YH used Excel tables for statistics at that time, but in order to save and backtrack, the factory had to print all the quality inspection data into paper sheets and keep them for three or even five years. It was not only troublesome to keep them, but also had to rely on manual statistics to count them regularly.

Until last year, YH found that the "approval function" of WeChat can directly record quality inspection data and complete the audit of production management in the process of patrol inspection. More importantly, these audit data are electronically marked and can be exported at any time 。

The approval function of WeChat helps enterprises complete various internal online approvals quickly. In the enterprise WeChat background, administrators can easily find approval templates suitable for various scenarios and create approval forms according to business needs. In the past, paper-based processes that required cross department communication, confirmation, and signature and approval can now be simply operated on mobile phones to help enterprises truly realize the digitalization of the approval process.

In addition to improving quality inspection efficiency, Vice President Hua found that for manufacturing factories, the "approval" function of WeChat can also play a role in many different production scenarios 。

From raw materials to finished products, there are many links that need manual inspection 。 For example, the first thing to go back to the factory every day is to check the effectiveness of machinery and equipment; After the arrival of raw materials, incoming inspection is required; During the production of parts, the in-process inspection shall be carried out regularly; After the product is ready, the product reliability test should be completed.

In the past, each inspection mentioned above was registered by the corresponding personnel. After being submitted to the department head for review and signature, some of them still need to be returned to another department for feedback, and finally archived for confirmation. In order to confirm and sign in time, employees and supervisors have to go back and forth several times in the factory every day. Now, YH has put more than half of the approval process in the factory online through the "approval" function of WeChat, reducing more than 15 paper reports 。

Digital audit is such a small change that the efficiency of the whole production workshop is improved 。

"Start with the simplest details and the most daily links" This is the inspiration YH got when promoting the digitalization of the factory.

For example, the most common payslips used to be printed in paper and then cut into thin strips, which is not only troublesome in the production process, but also inconvenient to keep 。 For this reason, employees of the HR Department have to spend a whole day every month to check, print, cut and distribute. Moreover, many workers can easily lose their payslips after they receive them every month. One day, they suddenly want to check the specific salary of the previous months. They often can't find all the payslips after rummaging around, and they have to ask personnel to check again.

For this reason, Vice President Hua once considered purchasing an app specifically used to record salary payment, but considering that the company now has fewer than 100 employees, after careful calculation of the cost, he decided to stick to it.

This is also a dilemma faced by many small and medium-sized factories. There are indeed many difficulties in doing all kinds of trivial things. Although digitalization can solve this problem, in order to save money, they will finally use traditional methods.

At this time, Vice President Hua found that WeChat itself had the function of "payslip" 。

It is with WeChat, a portable and easy-to-use tool box, that paperless office work becomes possible for YH.

Payslip is the most important thing that manufacturing workers care about. It can better reflect the value of paperless office. It is the production task arrangement.

In the era of paper-based office, the daily production task arrangement of the workshop is a work with tight time and heavy tasks ——Before arranging the tasks of the next day, the production supervisor should wait for the employees to file the output and order completion of the day in paper and enter data. After the results are counted, the production scheduling of the next day can be arranged according to the results of the previous day, and then the tasks can be written on the whiteboard of the workshop.

In this way, not only time is tight, but if the supervisor wants to make more detailed production adjustment according to the yield rate, he can only wait until weekly or even monthly summary, and the feedback process is quite lagging.

But now, the output and inspection data of each time period can be fed back in real time on the WeChat data board of the enterprise and displayed in the production workshop through the large screen. This not only facilitates the supervisor to make task decisions for the next day in advance, but also makes the adjustment of the production line more flexible 。

"When the order comes, we can start work immediately. Short production cycle and tight pace are the biggest advantages of small and medium-sized factories." Vice President Hua said 。

The flexible back is a large number of upstream and downstream cooperation: Small and medium-sized factories can only complete one link of the whole production and manufacturing. There are still many links that need to be entrusted to other factories. If the production pace of these upstream suppliers is not well controlled, it will slow down the completion of orders 。

Taking the conversion plug produced by YH as an example, the production generally requires three steps: stamping, injection molding and assembly. among The last two links can be completed by YH itself, but the stamping link needs to be entrusted to other factories for technical reasons.

For the manufacturing industry, there have been some preliminary solutions for upstream and downstream cooperation: as early as the 1990s, the Manufacturing Execution System, MES) has been introduced into China. Now, most of the large domestic manufacturing factories have successfully completed the digital transformation with the help of MES.

However, for many small and medium-sized factories, it is not easy to use such a system. On the one hand, MES with complex functions is more complex to use, and some advanced functions may not be used or used by some factories; On the other hand, not every factory can afford the expensive use cost 。

So, back to the previously mentioned dilemma, which can be digitized but has high costs, many small and medium-sized factories finally have to use traditional methods to solve it.

However, since the beginning of this year, YH has added a small assistant in its production workshop, that is, the "self built application" of WeChat 。

Self built applications refer to the simple development of enterprises themselves to connect digital applications suitable for their factories to enterprise WeChat, so that workers can open enterprise WeChat to use them, and realize digital transformation in a lighter and easier way.

With the help of the service provider, YH started to move the entire production process to the online at the beginning of this year, which also brought some surprises.

In the past, YH's assembly workshop had to wait passively for the other party to deliver the parts. The specific time could not be determined, and the production rhythm was difficult to coordinate, so it was easy to delay working hours. It is often because YH's workshop is ready, but the other party has not finished it, or the other party has sent it in advance, but other parts of YH are not ready.

"We don't need too complicated functions. Now it's just good. Simple and easy to learn, the cost is acceptable." Vice President Hua told us 。

In YH, we have seen another side of the traditional manufacturing industry, not only the amazing speed of China, but also in the production chain, we have done a good job in every link and every account seriously. In pragmatism, we can see more wisdom.

In such a hot summer day, we witnessed the production of a "data line connector"; In the future, WeChat is also expected to become a bridge to connect more small and medium-sized manufacturing enterprises, helping them achieve extraordinary micro achievements 。
