Every Process Must Stand The Test – In Memory Of "Shaanxi Fei Outstanding Employee" Liu Liangyu

Every process must stand the test – in memory of "Shaanxi Fei Outstanding Employee" Liu Liangyu

After the fighter aircraft has been riveted and welded, the team responsible for the painting construction on site are most afraid of encountering a tight construction schedule, difficult to control color aberration problems, and very difficult masking operations. Liu Liangyu, a spray painter at the final assembly plant of Shaanxi Aircraft Industry Company, has to make every process stand the test – remember Liu Liangyu, "an outstanding employee of Shaanxi Aircraft Industry". He used 30 test panels for three consecutive days for actual operation testing, and finally succeeded in advancing the delivery time of the product by 48 hours.

Zero defects is a tough rule

Be the first to arrive at work every day to check tools

He is the first person to walk into the factory every morning. He checks the spray guns, sanders and wind belts required for painting work one by one, in order to ensure that every tool used in the same construction position is in the best working condition.

Although the exhaust unit over there has been running rumblingly, and the smell of odor reagents and the sound of machine polishing are mixed together to make it unbearable and impossible to stop, he still adheres to his flawless belief and will never let go of any small detail in the production process.

Wing spraying failures occur frequently

The problem of wing surface spray failure has been a persistent headache for many years. He dared to boldly explore new process methods, and innovatively used the method of covering the entire upper surface and adding electrostatic spraying for multi-layer spraying. He conducted repeated construction verification operations at the construction site, and finally succeeded in improving the efficiency of spraying, ensuring that the aircraft paint surface was uniform and smooth.

Three days to gnaw down the hard nut of partitioning and color differentiation

Traditional solutions cannot keep up with delivery nodes

At that time, the cabin needed to be divided into areas and painted with colors. The pressure of the task was very huge and urgent, and the traditional construction methods in the past could no longer meet the delivery standards required now.

So he very proactively requested to join the team that was used to solve the problem, and then he worked hard day and night for three consecutive days to solve the problem. In total, he completed 30 pages of spray paint test work for testing process test panels, and thus launched a powerful offensive against that particularly hard nut.

Simulation environment repeatedly deduce parameters

He set up a simulated working environment for the team, repeatedly deduced the spraying parameters under different temperature conditions, and recorded the drying time, leveling effect and color uniformity of the paint surface very carefully. He made a series of suggestions for improvements and tested various masking tapes one by one to confirm their adhesion and peeling effect.

Screening out the best masking tape

Find the right material when it comes to epoxy paint

His goal was to get the epoxy paint surface to a state that would cover it perfectly. To this end, he conducted repeated comparative tests, tested a variety of sticky materials, and verified the adhesion strength and peeling effect under different spray pressures.

Through this series of actions, he finally selected a kind of tape. This kind of tape is a high-quality on-site spray painting construction team after riveting and welding . It can effectively shield and will not damage the quality of the underlying paint surface.

Multiple rounds of simulated construction iterations to the optimum

Relying on the optimized parameters and new materials, the team carried out multiple rounds of simulated construction. They continue to iteratively adjust the process until every detail reaches optimal standards. The final result was that after the riveting and welding process, the on-site painting construction team achieved high-quality and efficient delivery 48 hours ahead of the original construction schedule.

Hundreds of tests on the intake duct

Complex structure parts are difficult to chew

The structure of the aircraft air inlet is relatively complex, and the angles are constantly changing. He has gone through hundreds of experiments and figured out the techniques of spraying at different angles and different materials one by one, thus significantly improving the quality of the paint surface of the product.

New equipment reduces costs and consumption

He took the initiative to study the use of electrostatic spray guns, as well as specific maintenance methods, and accurately controlled the amount and scope of spraying, thereby achieving the goal of saving paint and reducing paint mist emissions. He also sorted out very detailed operating specifications, which greatly reduced the failure rate of the equipment.

Reusing materials saves real money

Recycling of flap cabin shielding materials

Relying on his rich practical experience, he repeatedly recycled and reused the materials used to protect the aircraft flap compartment from being contaminated by paint mist. On the one hand, this has improved the efficiency of material use, and on the other hand, it has actually reduced the company's production costs, thus allowing the concept of "saving" to be implemented in every process of production.

Personal experience becomes team standard

In his spare time at work, he sorted out and archived his practical experience one by one, and then refined it to form a new set of operating methods. After being promoted in the team unit, this set of methods was unanimously recognized by his colleagues. As a result, his personal experience was transformed into a construction standard used by the team.

The paint surface is the first face of a fighter plane

Keep craftsmanship between square inches of paint

The paint surface is the first face of the product, and every process must stand the test. He often said this in his mouth. A layer of paint represents a responsibility and obligation. He pursues more precision and perfection in every inch of the paint coating, and protects the original aspirations and beliefs through the spirit of craftsmanship.

Innovate and tackle key problems to improve quality and efficiency

He has achieved quality improvement and efficiency increase in the process of innovative research, allowing fighter planes one after another to wear strong and beautiful protective clothing, and protecting the quality of the equipment. On the production line of the Shaanxi Fei assembly plant, he is the most inconspicuous but most important magician role.
