Delta Engineering developed a new welding system on our bagging machines, resulting in perfectly tight bags, in line with DIN EN 11607-1 . This method implicates the testing of the bags with colored water.

Check weighing

A checkweigher is an automatic or manual machine for checking the weight of packaged commodities. It is normally found at the offgoing end of a production process and is used to ensure that the weight of a pack of the commodity is within specified limits. Any packs that are outside the tolerance are taken out of line automatically.

Checking neck calibration issues in extrusion blow molding can be easily done with our DVT100. Instead of filling bottles with water and inverting them, and then waiting for several hours to see if a water leak on the neck appears, the DVT100 is a better alternative.
The cap leak test can be done in a very simple way.

Bottle closure tester

Unité de test de fermeture de bouteille

Delta Engineering a développé un testeur de fermeture de bouteilles très simple: il s’agit d’une chambre à vide dans laquelle sont mises des bouteilles remplies d’eau. Le tissu de papier en-dessous des bouteilles indique la moindre fuite! Dès que le testeur est fermé et a été démarré, il crée le vide dans la chambre où se trouvent les bouteilles. L’état à vide désiré atteint, la consommation énergétique et d’air sont terminées. Ceci vous permet de contrôler (pendant la production) si la fermeture de vos bouteilles est 100% étanche ce qui vous aide à éviter les plaintes et les réclamations des clients.

In Extrusion Blow Moulding (EBM), plastic is melted and extruded into a hollow tube (a parison). This parison is then captured by closing it into a cooled metal mold. Air is then blown into the parison, inflating it into the shape of the hollow bottle, container, or part. After the plastic has cooled sufficiently, the mold is opened and the part is ejected.

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum. It is sometimes called “alkathene” or “polythene” when used for pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes, and plastic lumber. HDPE is commonly recycled, and has the number “2” as its resin identification code (formerly known as recycling symbol).

Redundant line design is very important if a highly efficient line is wished for. This article is about a high speed PET bagging line, witch is designed in this way. We will discuss the OEE definition and practical interpretations, advantages of bagging and , pallet stability, last but not least the line concept in detail.

The process of injection blow molding (IBM) is used for the production of hollow glass and plastic objects in large quantities. In the IBM process, the polymer is injection molded onto a core pin; then the core pin is rotated to a blow molding station to be inflated and cooled. This is the least-used of the three blow molding processes, and is typically used to make small medical and single serve bottles. The process is divided into three steps: injection, blowing and ejection.

Spray coating Spray coating is a technology used to coat the surface of the bottle to improve the sliding and brightness properties of the treated bottles. This is a very effective method in comparison to additives inside the bottles or preforms, as it doesn’t affect the material properties. Often , additives have an impact on

This article describes a test setup in a theoretical model to measure the impact of the flushing air, and evaluating the cost of the compressed air against the cooling coefficient gain.
