Prominent Pet Preform Manufacturers use many measures on quality control to ensure high quality of the PET preforms. These measures start right from the selection of the raw materials up to quality check regulation of the finished products.
Here are some key quality control measures commonly adopted for Pet Preform Manufacturers:
1. Raw Material Inspection
– Supplier Qualification : Negotiating and maintaining that the suppliers supply us with quality PET preform that meets set standards.
– Batch Testing : Performing tests on every received batch of raw materials for characteristics such as; viscosity, moisture content, and contaminants.
2. In-Process Quality Control
– Melt Flow Index (MFI) Testing : Supervising the rate of the PET flow in the mould to such a parameter that is best suited for molding.
– Temperature Control : Ensuring that one controls the temperatures upon injecting the parts to avoid some common defects.
– Injection Pressure Monitoring : Some of the parameters that need to be controlled in order to manage the MPP of preforms include;
3. Dimensional and Visual Inspection
– Automatic Vision Inspection Systems : To control the visual imperfections like the formation of bubbles, spotting or any sort of surface blemish; cameras and software are utilized.
– Dimensional Checks : Using standard measuring instruments including calipers and micrometers in order to determine the critical dimensions of the item including the neck finish, the wall thickness and length.
4. Mechanical and Physical Testing
– Tensile Strength Testing : Evaluating the appropriate tensile strength of preforms to make sure that preforms bear the stress which is exerted during blow molding.
– Top Load Testing : Measuring the ability of preforms to maintain shapes with changes of axial loads.
– Burst Pressure Testing : The ability to prevent such preforms from failing under internal pressure as is the case with carbonated beverage bottles.
5. Chemical Testing
– IV (Intrinsic Viscosity) Testing : Determining the intrinsic viscosity to determine the molecular weight and making sure that it falls within the specified range.
– Acetaldehyde Content Testing : To ascertain or control presence if acetaldehyde in the post treatment packaging product that may alter taste and odor.
6. Quality Management Systems
– ISO Certification : The organization implements quality management system according to ISO 9001 or food safety management system according to ISO 22000.
– Statistical Process Control (SPC) : Applying statistics tools to keep the observation and command of manufacturing process in order to decrease variation and increase stability.
– Total Quality Management (TQM) : Applying strategies which will help in achieving the goal of maintaining culture of improvement in all the organizations.
7. Traceability and Documentation
– Batch Tracking : Essential records should also be kept with each production batch in order to track product errors or recalls if needed.
– Documentation and Reporting : Proper documentation of all the quality control activities, the tests conducted as well as the action taken in case of a problem encountered.
8. Employee Training and Development
– Regular Training : Conducting perpetual training programs to employees to make them understand on quality control techniques and the significance of quality control.
– Skill Development : The training programs can comprise of offering workshops, certification courses and other exercises to boost the competencies of the employees.
From the following measures, it is clear that the leading Pet Preform Manufacturers in India have to meet the market value that is expected by the various users or market segments such as food and beverages, pharmaceuticals, and the personal care industry among others.
