Path of Quality Development

n our process of implementing “Total Quality Management,” we are guided by our business philosophy and customer needs. We have insisted on adherence to quality, continuous improvement, technological innovation, and that customers come first. We focus on the management of processes and details while constantly improving different aspects of our operations such as R&D, marketing, management and so forth as we continue to advance towards our vision of “building a world-class company with firm profits and steady growth in the industrial safety component business.” We have separated our journey into four specific stages, with the history and results covered in the following section.

Quality inspection stage Description For our business model as a trader, we prioritized the selection of high-quality, third-party manufacturers and through supplier assessment and audit, we ensured consistency between product quality standards and what our customers expect in order to satisfy customers’ needs.
Activities and results Supplier assessment, supplier audit
・External quality verification for quality assurance
Quality manufacturing management stage Description Established our production base and focused primarily on stable quality and rapid production. During this period, we introduced a quality management system that met our customer requirements and a testing center laboratory verified our facility to validate the accuracy of tests we perform.
Activities and results ・Committed to the development of Grade 80 hooks in 1997
・Established our own testing center and introduced non-destructive testing of magnetic particles
・Obtained certifications for API QMS ISO 9001 and API Specification Q1
・Product manufacturing assessments: ABS, API, CCSS
・Product type certifications: ABS, DNV, DGUV and SGS
Quality design for prevention stage Description With the altruistic philosophy of “win-win-win” (i.e. customers, suppliers and YOKE), we actively promoted the importance of preventive management. Externally, we advocated at the supplier conference that SPC could be utilized to detect and reduce NG products preemptively to boost productivity and reduce costs; internally, we introduced an advanced product quality plan (APQP) to achieve early identification of quality issues and take preventive measures to avoid losses from later changes while delivering quality products to customers in a timely manner.
Activities and results ・Became a leading brand for Grade 100 hook products in 2010
・Inspected and calibrated relevant equipment and apparatus; introduced tightened and reduced planning system
・Promoted operation of the quality management system and relevant internal/external audits
・Provided quality and defect analysis and feedback; offered assistance to our suppliers
・Established our R&D center and jointly established R&D center with National Taiwan University to complete our development of Grade 120 materials
・Introduced various systems including MES, PLM and Salesforce
・Introduced the concepts of 5S, continuous improvement activity group (CIT) and TPM
Quality excellence sustainability stage Description In 2016, we promoted the cultures of “total participation and continuous improvement” at YOKE. Since then, we have been organizing the continuous improvement activity group competition on a yearly basis to use the 8D problem-solving model for the analysis and improvement of issues. During the mid-term and end of year, we carried out audits to improve efficiency. At the end of the year, we would also invite outstanding suppliers to participate in the activity to inspire other suppliers to attend. At this stage, we expected the quality culture we had been building to positively influence our employees’ values and conduct and boost their work performance and acclimatize them to adhering to the processes and instructions of quality management. Ultimately, we hope employees can eventually reach the state where quality is simply a product of “habit.” In order to help employees become more quality conscious and achieve the goal of total participation, we have been organizing factory-wide SOP tests on quality and all employees (the general manager included) quarterly starting from 2019.
Activities and results ・Organized factory-wide SOP test on quality
・Introduced SPC system to digitize QA data for easy management and quick response
・Introduced 3D scanner to refine inspection and measurement accuracy
・Digitization at our laboratory
・Full-fledged promotion to become the leading quality for Grade 120 hooks
・Obtained environmental, safety and health certifications (ISO 14001 and ISO 45001)
・Expansion of industry-academia collaborations

Product Regulations

After design and development are completed according to applicable product regulations that are reflective of the characteristics of products such as offshore energy, construction, material handling, and mining-oriented Grade 80/100 chains, steel wire ropes, and webbing accessories, wire rope terminal sockets, shackles, yellow snatch blocks, and personal safety harness fittings are designed, developed and manufactured.

As is required by regulations, we have submitted applications to the following certifying institutions to have the mechanical testing (pulling force) completed for products in respective series in order to ensure that products meet regulatory requirements and the needs of customers:

  • 加拿大標準協會

    Canadian Standards Association, CSA

  • 挪威驗船協會

    (Det Norske Veritas, DNV)

  • 美國安全驗船協會


  • 德國社會意外

    (DGUV Test)/CE0299

  • 英國製鞋技術


Product Testing Verification

Product safety regulations promoted by relevant international organizations have always been the focus of attention for YOKE. As such, the Product R&D Department has been maintaining positive interactions with said organizations. In addition, YOKE has established rigid internal control over the versions of international standards so that we can keep track of related information as soon as the regulations are supplemented or revised.

For products in the N series that may be sold directly, we can have 100% of the products complete relevant testing before a customer places a purchase order to meet the customer’s needs. However, for parts and components that are terminal products, there is no testing and verification mechanism available as they are sent for testing and verification by the customer after they are assembled as the final product.  For the 8 series of products, on the other hand, the needs for product qualification are tested and verified according to market sales and customer requirements. Among the 12 major categories, 4 are 100% sent for testing and verification while another 8 are tested based on the customers’ actual needs. Analysis of our 2020 revenues shows that the 4 major categories that are 100% sent for testing and verification accounted for up to 85.54% of our 8-series products, and the percentage had remained over 80% in the past 5 years. This indicates that product safety qualification is of significant concern to our customers.

In order to ensure the safety and protection of users, in addition to the aforementioned quality management systems, factory qualifications, and product qualifications mentioned above, YOKE has had its products covered by liability insurance, with insured value up to USD 5 million for more than 10 years to offer even more additional protection to users. No product safety-related events that resulted in an undermined corporate image of YOKE occurred in 2020.

Change of standards

Most of the products distributed by YOKE are required to be compliant with specific product specifications established by relevant international institutions. And as such, the Quality Assurance Department will check existing laws, regulations and specifications on a quarterly basis and prior to external audits to ensure we are up to date with the latest versions. In light of product and market demand, we have acquired a copy of EN 134141-1:2020-03 specification for our 8-series products and 7 copies of CNS 14253-4 specifications for our SRL products. As of the end of 2020, our 8-series products are compliant with 59 product standards, while our N-series and SRL products conform to 32 standards, along with 22 systems and testing standards. Some policymakers have actually contacted us to decide whether a specific revision of a standard/policy was feasible before proceeding with the actual change.

In the event of a change in product standards, the Product R&D Department is required to compile a difference analysis report that identifies and assesses risks to the quality of products manufactured. And after performing relevant tests for the changes in question, the department then needs to explain to the Product Center, the Quality Assurance Department and manufacturing-related personnel about the changes involved in order to mitigate the impact of changes on the Company and its products. After we have confirmed the feasibility of the proposed changes, we would either go with the product design or initiate a change.

Digitization for quality control

In order to strengthen the efficiency of quality control, YOKE continues to expand the scope of its SPC system. After completing our laboratory testing and incoming supplier inspection in 2019, we introduced in-process testing and end-product testing while integrating our laboratory apparatus into the MES system at our factory. This could reduce approximately 100,000 sheets of incoming material slip and inspection record forms per year. Not only that, it would also reduce the duration of manual labor performed by approximately 1,200 hours each year.

Laboratory establishment

As we are obliged to prioritize the veracity of our product safety testing, our laboratory performed 11 tests in accordance with pertinent international product specifications. For more than 10 years, the laboratory tested our products according to ISO/IEC 17025 laboratory quality management system specifications. In an effort to improve the accuracy and credibility of our laboratory testing, the laboratory at Factory 2 had also been certified to ISO/IEC 17025:2017 standards in January 2020.

In light of the fact that dynamic fall tests for products had to be commissioned to overseas laboratories, the test would usually take 2-3 months to complete. In 2020, we introduced a new dynamic fall test (ANSI/ASSE Z359.14) for our laboratory and we went through the certification process for ISO/IEC 17025:2017. This helps us save time and money to have the test performed abroad as we can now perform it quickly and conveniently at our own laboratory.


Safety is our first priority and
