Production Flow

I

Set clear quality goals

Based on customer needs, industry standards (such as ISO, GB, etc.) or internal specifications, clarify key product quality indicators (such as dimensional tolerances, performance parameters, appearance defect standards, etc.) and form written documents to ensure understanding by all employees.

II

Standardized production process

Develop SOPs for each process (such as raw material inspection, assembly, and packaging) to clearly define the operating steps, tools, parameters, and qualification standards to avoid human operational differences.

III

Strict supplier access and auditing

Establish a supplier evaluation system (e.g., quality stability, production capacity, and compliance), conduct regular audits (on-site factory inspections and historical quality data), and eliminate unqualified suppliers. Sign quality agreements with core suppliers to clearly define raw material quality standards and liability for breach of contract.

Incoming Raw Materials Inspection
IV

Incoming Raw Materials Inspection (IQC)

All incoming raw materials and parts undergo sampling or full inspection, and are judged as qualified according to standards. Unqualified products will be rejected or returned.

V

In-Process Quality Control (IPQC)

1. First Article Inspection

Before each shift and after mold/material changes, the first piece is fully inspected. Only after passing the inspection and documenting its compliance can mass production begin to avoid batch errors.

First Article Inspection

2. Patrol Inspection and Random Inspections

Quality inspectors regularly patrol each process, randomly sampling according to a certain percentage to check for compliance with SOPs and quality standards, and promptly identify anomalies.

Patrol Inspection

3. Equipment and Tooling Maintenance

Production equipment and testing instruments (such as calipers and spectrometers) are regularly calibrated to ensure accuracy meets requirements. Tooling fixtures are maintained to prevent quality issues caused by equipment errors.

Finished Product Inspection & Defective Products Handling

1. Before finished products enter storage, they undergo standard sampling inspections to check appearance, performance, packaging, and other aspects. Only qualified products can be stored or shipped.

2. Defective products (raw materials, work-in-progress, finished products) are labeled and isolated to prevent misuse. An evaluation is conducted (cause analysis and responsibility determination), and a handling plan (rework, downgrade, or scrap) is developed.

Personnel Management and Quality Awareness Cultivation

1. Job Training and Qualification Certification: Operators receive pre-job training (SOPs (Standard Operating Procedures), quality standards, and inspection methods). Only qualified personnel can begin work after passing the assessment. Special processes (such as welding) require certification. Periodic refresher training reinforces quality requirements.

2. Establish a "Quality Responsibility System": Clearly define the quality responsibilities of each position (e.g., operators are responsible for the quality of their process, while quality inspectors are responsible for inspection results). Link this to performance appraisals and clearly define rewards and penalties. Encourage employee participation in quality improvement (e.g., providing rewards for making reasonable suggestions and discovering potential problems).

VIII

Quality Records and Traceability System

1. Record data from the entire production process: raw material batches, equipment numbers, operators, inspection results, etc., to ensure product traceability (so that quality issues can be quickly identified).

2. Hold regular quality meetings to calculate defect rates, analyze frequent issues, and identify root causes (e.g., equipment, materials, or operation).

3. Promote the PDCA cycle (Plan-Do-Check-Act): Develop corrective actions (e.g., updating SOPs, changing suppliers), verify effectiveness, and standardize to prevent recurrence.

FAQ

FAQ support banner
What is a Split Set Rock Bolt and how does it work?
A Split Set stabilizer is a slotted steel tube with one end tapered for easy insertion into a drill hole. The other end has a welded ring flange to hold the bearing plate. It is driven into a slightly smaller hole, generating continuous frictional support along the entire length of the tube against the rock walls.
What are the standard dimensions and options for Split Set Rock Bolts?
Our Split Set rock bolts come in nominal outside diameters of 33mm, 37mm, 42mm, and 47mm. The standard length ranges from 1 to 3 meters, and the wall thickness is available from 1 to 4mm. Both parameters are fully customizable based on project specifications.
Do you offer corrosion-resistant options for corrosive environments?
Yes, we provide hot-dip galvanizing with a coating weight ranging from 430g to 600g per square meter. The coating specifications can also be customized to adapt to corrosive mining or civil engineering application environments.
Which quality standards and certifications do your anchoring systems meet?
Our anchoring systems and production facilities comply with major global frameworks, meeting requirements under ISO, MSDS, SGS, FCA, GOST, and CE standards. We follow strict quality guidelines, including IQC and IPQC procedures, to ensure consistent and reliable performance.
Can you provide customized anchoring solutions for unique project challenges?
Yes. In addition to standard sizes, we offer in-depth customization services. We precisely adapt products to comply with national standards and meet diverse regulatory requirements, creating tailored anchoring solutions for unique project applications.
What is your production capacity for handling urgent or large orders?
We run multiple intelligent, parallel production lines simultaneously. This system supports large-volume orders and increases daily production capacity by up to 300%, ensuring rapid delivery of urgent orders and an uninterrupted supply during peak seasons.
