The PET bottle manufacturing, bottling, and packaging industries swear by the Bottle tester instruments. Let’s see why bottle inspection equipment is needed in the industry.
It is crucial to evaluate every component of these bottles because PET bottles are frequently used to hold a variety of beverages. We always make it simple to deliver high-quality items, whether you’re looking for glass inspection products, inspection products, or HDPE bottle inspection equipment.
The polyester material PET, also known as polyethylene terephthalate, can be extruded or moulded into a wide range of shapes, including plastic bottles, food containers, and other consumer goods. PET offers a cost-effective, non-reactive, shatterproof alternative for transporting liquids, food, and consumables because of how strong yet light it is. All bottles made at the facility can be verified and tested for functionality using a functional leak test process.
Additionally, testing safeguards inventory, supervises the entire blow moulding process, averts costly returns, and prevents sporadic quality problems that spot checks occasionally miss.
High-speed PET blow moulding machines are used to manufacture the majority of transparent bottles. Sodas, water, sports drinks, juices, speciality beverages, ready-to-drink teas, dressings, sauces, cooking oils, mass-produced glasses, and cleaning supplies are examples of common bottle kinds. This method is excellent for producing transparent containers with perfect finishes quickly and efficiently.
Several factors drive PET bottle leakage testing
- Functional testing to confirm that the pressure is kept constant and that each cylinder is leak-tight.
- Identify the most significant errors quickly.
- Protection from unintentional quality problems with 100% total control.
- Keep an eye on the blow moulding procedure.
To promptly detect leaks and notify the operator to take corrective action, a leak tester is often installed as the second machine following the blow moulding machine.
Leak testing for PET bottles and typical flaws
The mass manufacture of PET bottles contains a wide variety of flaws. Even the smallest error might have unfavorable effects and lower the caliber of the final output. Look for the following types of flaws while inspecting bottles for leaks:
- Seal-related defects (shorts, cuts, bent necks, etc.) – Each sealing surface is functionally examined during the leak test by sealing and pressurizing each vessel. Low seal forces and precise seal surface testing are made possible by ALPS’s utilization of the lowest test pressures available in the market. To guarantee the integrity of the most important seal-related flaws of a certain vessel, different probe seals (softer or harder) and probe designs (solid, angled, etc.) can be provided.
- Holes (such as sprue holes, sprue cracks, contamination flaws, and incorrectly formed bottles) – Pressure-based leak testing detects leaks independently of their location or appearance. The gate, or injection point at the bottom of the container, is the most typical weak spot for tiny leaks in PET containers. If there are problems with the materials (such as contamination from recycled materials) or process issues that affect the proper formation of the bottle, leaks can occur anywhere in the bottle.
- Height and Top Load – The leak tester can be fitted with an additional inspection device that detects the height of the container and ensures that the container is not deformed at the specified sealing force (top load).
