As a customer, you like to choose a partner that guarantees the stable and continuous quality of PET bottles and jars. Thanks to the advanced production environment, AGI Plastek is able to meet almost all customer requirements. In addition, we regularly invest in the latest injection blower machines, in automation, and in control equipment. By applying the LEAN Manufacturing philosophy and Sigma 6 projects, we continuously improve our production processes.

High-quality raw materials
The same approach is reflected in the selection, purchase, inspection, and use of raw and auxiliary materials. Suppliers are regularly assessed and audited. We strictly check incoming goods and during production, we ensure that the products meet the agreements made with our customers.


The production process in 3 steps
AGI Plastek mainly uses the ISBM production technique (Injection Stretch Blow Molding). The majority of the production is made via a single stage technique. One and the same machine makes the basic form (preform) and the final PET bottle or pot. This method is extremely suitable for both small and larger series. The process goes in three steps.

Step 1: Towards the basic form (preform)
The PET granulate (the raw material) is dried. Then it goes through a helical cylinder from the dryer to the machine. During this transport, the granulate granules are heated, resulting in liquid PET. With normal PET, the transparent brightness is created in this phase. If desired, dyes are added to get colored material. The liquid mass is then injected into the first mold: the so-called preform mold. This way the neck of the bottle or jar gets the exact size in one go and the jar or bottle as a whole gets the right weight.

Step 2: To the final form
The basic shape now gets a neck sprayed with high precision. The basic form then goes to the next station via a turntable. With a number of machines, this is a station for conditioning this basic form. This, for example, to further optimize the temperature profile. For other machines, this preform goes directly to the blowing station. The blow mold gives the basic shape its definitive shape by stretching and blowing out the elastic part under the neck. The dispensing is done with a dispenser pin that brings the material to the bottom. Blowing causes the PET to form against the wall of the blow mold, which can produce all kinds of shapes and motifs.

Step 3: to the end product
In this step, the product goes to a final station in the machine. Here, a removal unit places the PET bottle or jar on a conveyor belt on which a leak check is carried out, the last step before the packaging phase. There may also be a visual inspection and possibly additional visual inspection via a camera. The checks are related to the customer’s coordinated requirements. After this, the end products are packed in boxes or on pallets. PET Power applies codes for storage and shipment.
