Brand Story

The inception of the JM Hardware® brand was a profound moment born out of a fateful business trip. During a trip abroad, I was flipping through a newspaper when I came across a heartbreaking story about a steel building that had collapsed due to a batch of substandard fasteners. The tragic images and casualties left an indelible mark on me.

From that moment on, our commitment to putting product quality first became a cornerstone of JM Hardware®, engraved in the DNA of our brand. With this unwavering commitment, JM Hardware® set out to set a new standard for quality. We spend countless hours researching, developing, and testing each product to ensure that they not only meet industry standards, but that they also meet the company's own higher standards. This journey is driven not by profit, but by a deep sense of responsibility - the responsibility to protect a person, a family, a community.

JM Hardware® stands as a testament to that enduring commitment. Every product that bears the JM Hardware® name will be synonymous with excellence, durability and safety.

JM Hardware®: the combination of quality and integrity.

JM Hardware conducts product quality control in strict accordance with ISO 9001 standards to ensure that our products meet high quality standards. Below are our five quality control steps:

Step 1: Incoming material control

We carry out strict incoming material control by conducting dimensional tests on each batch of raw materials and checking the raw material reports from the steel mills. This ensures that the raw materials we use are within specification and provide a reliable basis for production.

Step 2: First part control
After the mold assembly is completed, we conduct a thorough inspection of the first production part and make detailed records. Only qualified first parts can be released to start mass production. This step ensures that the quality of the product meets the standard at the beginning.

Step 3: Self-inspection by workers during mass production
In the mass production process, we require the workers of each machine to carry out self-inspection every hour. If any substandard product is found, we will immediately pick or scrap the production within this hour until the problem is solved and meets the standard of conformity, and then we can continue the production. This self-inspection mechanism helps to find and solve problems in time during the production process.

Step 4: QC inspection during mass production
In addition, every two hours, the quality inspection personnel will carry out random inspection on the products of each machine. Only qualified products can continue to flow into the next production stage. If non-conforming products are found, we will take the same selection or scrapping measures and ensure that the problem is properly handled. This helps provide additional quality assurance.

Step 5: Finished product control
Finally, after each batch of finished product is made, we conduct random inspections in proportion to the order. Qualified products will be packaged and put into storage, while unqualified products will be returned for further analysis and rectification. We insist on ensuring that the quality of our products meets high standards so that we can provide reliable products to our customers.

Step 6: Non-conforming goods management
According to the process of JMhardware's non-conforming products handling, pick or scrap. And the problem of rectification and tracking reasons to ensure that non-conforming products will not flow into the market.

These quality control measures constitute JM Hardware's quality management system, and we are constantly striving to improve the quality of our products and are committed to meeting the needs of our customers. We believe that quality control is the key to our success.
