In manufacturing enterprises

Dispersed operating standards are obstacles to corporate efficiency improvement

Like invisible barriers, hindering collaborative development between departments

Differentiated working methods also limit the group's scaling process

Chairman Xue of Chunqiu Group proposed at the beginning of this year

" One Chunqiu, One Standard ”  as the core strategy

This eight-character maxim

Though simple in words, its meaning is profound

Directly points to the key of group development

By unifying manufacturing technology and operational management

Reducing barriers between manufacturing bases

Achieving optimal resource allocation and efficient collaboration

However, the implementation and rooting of unified standards rely on strong group-level operations and lean manufacturing capabilities.

To this end, the group further clarified "Strong Operations, Lean Manufacturing" as a strategy, serving as a deepening of the standardization concept and an action guide.

" Strong Operations ” Aims to build group-level systems and standardized processes to achieve cross-base collaboration; "Lean Manufacturing" Refers to promoting product precision, process refinement, and talent specialization, comprehensively enhancing the group's manufacturing hard power.

" One Chunqiu, One Standard ” Its proposal marks the group's development entering a new stage of standardization and systematization 。

 

 

Chairman Xue said

"One Chunqiu, One Standard ”

" Strong Operations, Lean Manufacturing ”

" To do a good job, one must first sharpen the tools ” To realize " One Standard ” Blueprint, it is necessary to Build a standard system covering the entire product manufacturing lifecycle 。 The standard project team closely follows manufacturing logic, starting from mold development, coordinating forming processing, and systematically planning seven key standardized modules for the pre-process.

First, mold opening standards take precedence. To build a unified standard system framework, detailed specifications have basically been formed for mold design, processing, assembly, acceptance, mold repair, and even scrapping.

Second, forming process automation equipment and jig standards unified For the product forming stage, technical specifications for robotic arms, feeding systems, removal equipment, and supporting jigs are unified.

Third, tolerance standards for in-mold embedded copper pins and mold Pin size standards unified. Copper pins, as inserts placed inside the mold for injection molding, have allowable tolerance ranges for position, height, and angle on the finished product. Regarding mold Pin size standards, requirements for the size, precision, and material of positioning pins used to locate inserts (copper pins) on the mold are specified. This is a standard for key parts of the mold tool. It directly affects the accuracy of in-mold embedded pins. Pins This is a standard for key parts of the mold tool. It directly affects the accuracy of in-mold embedded pins.

Fourth, automation solutions & jig solution standards unified. Implementing automation in manufacturing, such as intelligent machine applications, and determining the overall plan for using corresponding jigs in design. This set of standards is not limited to the mold itself but revolves around the production process.

Fifth, processing line procedures and labor efficiency standards unified. This standard unifies post-processing steps such as deburring, grinding, punching, cleaning, assembly, testing, packaging, operation methods, and labor efficiency standards.

Sixth, copper pin inspection definitions unified. Belonging to quality inspection aspects Clearly defines how to inspect the quality requirements of copper pins, whether embedded in the mold or assembled later, including inspection items such as position, height, appearance, conductivity, as well as inspection methods and judgment criteria. This is a quality control standard serving quality assurance throughout the production process.

Seventh, in-mold embedded pin jig standards unified. Embedded pin jigs are a type of jig Specifies design, manufacturing, and usage standards for specialized jigs used to accurately and efficiently place copper pins in designated mold positions during the in-mold embedding process.

Standardization of die design

"The road is long and arduous, but walking will get you there"

The strategic implementation of "One Group, One Standard"

Is destined to be a tough battle

Chunqiu Hefei Manufacturing Base's

Become the frontline position in this tough battle

Unified die design, with " High precision ”  and  " Automated adaptation ”  as the two core elements.

From Material selection, structural design, process flow to refined Gap control and Positioning methods all strive for high consistency. Mold design standards need to be based on product characteristics, Manager Fang Chengwei's stamping die design team has organized personalized workstation data and specifications according to different product categories, drawing clear workstation maps for the four major types of stamping dies.

Among them   A parts have a total of  17  categories  19  workstation points; C parts   has a total of  9  categories  21  workstations; D parts  22  product categories, 21  workstation points;  A/D magnesium plate heating parts   has a total of  3  categories, 8  workstation points.

The unified standard process for stamping dies covers stamping, CNC machining, grinding, sandblasting, anodizing to post-processing assembly, packaging, shipping, and other full-chain required equipment and automated processing with detailed prescribed handling processes.

2024 At the beginning of the year, the stamping die design at the Spring and Autumn Hefei manufacturing base, Boda plant, began practicing unified standards, cooperating with the introduction of automated production methods. Manager Fang Chengwei of the stamping die design team deeply feels: " The improvement brought by automation is very significant. Efficiency has increased, errors caused by human oversight in workstation omissions have decreased, and production is more refined and controllable. ” He uses C the keyboard hole stamping process as an example to explain how the automated process directly replaces manual blowing operations, greatly reducing waste and defects. While efficiency leaps, labor costs sharply drop, from 15-16 workers reduced to 6 workers, a reduction of up to 70%。

However, the road to standardization is not entirely smooth.

"In June 2024, during the initial introduction of magnesium plate products, the team still lacked sufficient mastery of magnesium-containing material characteristics and processes. During the magnesium plate 17Z90Q product trial mold, there was a communication deviation with the business PM; a cold mold was used instead of the required hot mold, failing to meet customer requirements." The unified standard for magnesium plate temperature control became a huge challenge.

But rapid response and learning are the keys to solving problems ." At that time, the team quickly adjusted mold temperature, updated reports, actively communicated with customers, and completed corrections within two weeks, avoiding losses in the subsequent mass production phase. ”

Manager Fang said, " This experience not only deepened the team's understanding of magnesium material temperature control but also trained the team's adaptability and learning ability, laying a valuable practical foundation for the unified standards of magnesium parts products. ”

Standardization of jig design

Jig design is a key engineering technology in manufacturing, mainly serving forming production processes, acting as auxiliary tooling, used to precisely locate, fix, support workpieces or guide tools during production or inspection processes It lies between product design and process design and is a key link in process implementation. Therefore, it is an important part of the group's unified manufacturing standards, capable of providing the entire process with high efficiency, quality assurance, and reduced operational difficulty 。

Manager Li Guanlong's team from the jig inspection department organized various jig standards for this unified standard project, among which, the embedded nail jig unifies four major dimension standards: lightweight design, key material specifications, positioning references, and core component models. A The cutting jig models and  model B   design standards unify the jig material grading, cutting parameters, jig positioning structure, and fixing methods, ensuring cutting accuracy and stability.

Additionally, there are standards for seven types of jigs including: shaping jig, milling head jig, hot cutting jig, stress wiping jig, and punching jig. Each jig has specific parameter requirements down to one decimal place regarding jig material, positioning, and structure. Taking the handling of material heads as an example, different products emphasize product structure, stress points, and cutting connection methods in design, cutting methods, and core components. emphasized product structure, stress points, and cutting connection methods The difference. The standard emphasized each fixture when established Design differences , truly practicing "Lean Manufacturing" The action guide.

When talking about the resistance encountered during project implementation, Manager Li recalled: " From the department 22 Year 8 Since its establishment in month, the Inspection Fixture Department has successfully transformed from relying on outsourcing to independent production, Gradually established standards for tooling fixtures in terms of specifications, weight, and vulnerable parts. In this process, The most impressive challenge was Balancing the lightweight and high strength requirements of the riveting fixture  。”

" Due to the fast production speed, certain core components and precision requirements of the fixture were high, The riveting fixture attached to the robotic arm had to be both lightweight and flexible, as well as sturdy and durable , so the workload of adjustment and optimization was a challenge for us at that time. Repeated adjustments involved the use and modification of various materials, and seasonal changes directly affected mold temperature variations, causing material deformation and resulting in fluctuating product quality. ”

Therefore, the fixture team and molding team went through multiple debugging and material parameter verifications, collaborating to overcome difficulties and finally found the best balance point.

This spirit of "pursuing excellence and mission accomplishment" is vividly embodied in the fixture team. When the rigorous craftsman's heart is integrated with the persistent pursuit of unified standards, it forges the strongest support for manufacturing upgrades.

The value power of "One Spring and Autumn, One Standard"

" Without accumulating small steps, one cannot reach a thousand miles. ” In fact, two years before the "One Spring and Autumn, One Standard" strategy was clearly proposed, the Mold Center of Hefei Manufacturing Base had already taken the initiative to explore unified standards.

To this day, department heads have organized, discussed, and summarized, gradually forming report-style standard manuals and initially establishing a unified standard action model. Everything needs to proceed step by step. Molding, assembly, painting, and other processes Will also, under the guidance of group strategy, gradually analyze processes, lean and standardize, and unify module processes. These reforms are interconnected and will eventually form a continuously optimized precision manufacturing closed loop.

The standardization system is like a source of fresh water, nurturing multidimensional value outcomes.

When production base orders fluctuate, relying on the group's unified standards collaboration can achieve Flexible production scheduling , achieving Cross-base optimized production layout. It can effectively improve production efficiency, Enhance equipment utilization rate, mold utilization, and response speed among manufacturing bases, Reduce production costs and save time costs, Extend mold life and also shorten the new product introduction cycle to some extent.

The standard system can not only expand the group's technical dimension, But also expand the management training dimension, Greatly shorten the new employee training cycle. Unified operating specifications allow new employees to "learn quickly, get started easily, and schedule flexibly." New and old employees work under the same framework, with consistent understanding and multiplied synergy. Unified production language, Can greatly reduce communication barriers across departments, Significantly improve labor efficiency standards. 。

"To flow far, one must dredge its source." These unified standard devices connected to the industrial Internet of Things gather into a structurally clear and reliable massive production data pool, Providing an indispensable "fresh water source" for the factory's intelligent transformation and application.
