Check weighing

Friday, 25 March 2016 by

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

Bottle closure test unit

Delta Engineering has developed a very simple bottle closure test unit. It consists of a vacuum chamber in which the water-filled bottles are placed on a tissue, indicating even the smallest leak.
Once the unit is closed and activated, it starts evacuate. When the desired vacuum is achieved, the energy saving system takes effect and disables the air consumption.
This enables you to test the bottle cap sealing in production, helping you avoid all customer complaints.

Bagging hoist

Delta Engineering developed some new bagging tools  : A simple tool to add on existing machines, allowing you more easy to position the base film roll during film change operations. A carriage who allows you to store a couple of rolls, together with a welding system. Interested ? Please contact our sales department per email

Extrusion blow molding

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.

Flat plastic sheets

Monday, 13 June 2016 by

Returning packaging solutions – Flat plastic sheets Over the years, we have developed together with our partners different packaging solutions for our customers, mainly focusing on returnable packing solutions because they have in most cases a fairly high return on investment. The first one we are discussing in this article is ‘ Returnable plastic flat

HDPE has SPI resin ID code 2

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).

Flat sheet - plastic pallet

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.
