What are the key quality control links in the production process of Quilted Throw?

1. Design stage
Function and design verification:
In the design stage, it is first necessary to clarify the functional requirements of Quilted Throw, such as warmth, breathability, comfort, and aesthetics.
The design team needs to make creative designs based on these requirements and produce design drawings.
After the design drawings are completed, they need to be verified and modified many times to ensure the rationality and practicality of the design.
The verification process includes simulating usage scenarios, testing warmth and breathability, and evaluating durability.
Material selection:
Choose suitable fillings and fabrics according to design requirements.
The fillings must have good warmth and breathability, and must be non-toxic, harmless, and environmentally friendly.
The fabrics must be soft, comfortable, wear-resistant, and easy to clean.
The selected materials must undergo strict quality inspections to ensure that they meet production requirements.
2. Raw material procurement and inspection
Supplier screening and evaluation:
Strictly screen and evaluate Quilted Throw suppliers to ensure that they have good reputation and product quality.
The evaluation content includes the supplier's qualifications, production capacity, quality management system, etc.
Raw material inspection:
Quality inspection of purchased raw materials, including fabric strength, filling density and warmth retention.
The inspection process must follow strict quality standards to ensure that the raw materials meet production requirements.
The inspection results must be recorded for subsequent tracking and inquiry.
3. Production process control
Cutting and sewing:
According to the design drawings, precise cutting and sewing are carried out.
When cutting, the size must be accurate and the fabric must be free of damage and defects.
The sewing process must follow strict process standards to ensure that the stitches are uniform, smooth, and free of defects such as skipped stitches and broken threads.
Quilting process:
Quilting is one of the key processes of Quilted Throw, and the quilting lines must be uniform and beautiful.
The filling must be evenly distributed before quilting to ensure that the blanket has good warmth retention after quilting.
During the quilting process, the equipment status must be checked regularly to ensure the quality and efficiency of quilting.
Cleaning and finishing:
During the production process, the working environment must be kept clean to prevent impurities from contaminating the product.
Clean and organize the finished products to ensure that they are neat and flawless.
The cleaning and organizing process must follow strict hygiene standards to ensure product quality.
4. Equipment maintenance and calibration
Maintenance of production equipment:
Maintain production equipment regularly to ensure the normal operation and accuracy of the equipment.
The maintenance process includes cleaning, lubrication, tightening and other steps.
Equipment maintenance records must be recorded for subsequent tracking and inquiry.
Equipment calibration:
During the production process, key equipment is calibrated regularly to ensure the accuracy of production parameters.
The calibration process must follow strict standards and procedures.
The calibration results must be recorded for subsequent analysis and improvement.
5. Quality inspection and sampling inspection
Finished product inspection:
Carry out a comprehensive quality inspection of the finished product, including appearance, size, warmth, breathability and other aspects.
The inspection process must follow strict quality standards to ensure that the product quality meets customer requirements.
The inspection results must be recorded for subsequent tracking and inquiry.
Sampling inspection:
Sampling inspection of finished products according to sampling standards to ensure the overall quality level.
The sampling and testing process must follow statistical principles to ensure the representativeness and reliability of the sampling results.
The sampling and testing results must be fed back to the production department and the quality department in a timely manner for timely adjustment and improvement.
6. Data analysis and feedback
Quality data collection:
Collect quality data in the production process, including raw material inspection data, finished product inspection data, etc.
The data collection process must follow strict data standards and formats.
The collected data must be timely, accurate and complete.
Data analysis:
Use tools such as statistical process control (SPC) to analyze data and promptly identify potential quality problems.
The analysis process must follow statistical principles and data mining technology.
The analysis results must be presented in the form of charts, reports, etc. for subsequent decision-making and improvement.
Feedback and improvement:
According to the analysis results, adjust and improve the production process to improve product quality.
The improvement process must follow the PDCA (Plan-Do-Check-Act) cycle principle.
The improvement results must be fed back to relevant departments and customers in a timely manner to verify and improve the effect.
7. Supply Chain Management
Supplier Management:
Continuously evaluate and manage Quilted Throw suppliers to ensure the quality of raw materials they provide is stable and reliable.
The evaluation content includes the supplier's qualifications, production capacity, quality management system, etc.
Eliminate and replace unqualified suppliers.
Logistics Control:
Ensure that raw materials and finished products are not damaged during transportation and arrive at the production site in time.
Monitor and manage the transportation process to ensure logistics efficiency and safety.
Promptly handle and solve problems that arise during the logistics process.
