Technology
At Plastimex we have the best technology for the manufacture of containers, in order to optimize our processes and maintain the quality of our products.
INJECTION MOLDING
Is a manufacturing process that makes it possible to produces components in high volumes. This works by injecting molten material into a mold and is often used as a mass production process to manufacture thousands of identical items.
How it worked?
The first stage is to create a mold itself, most of these molds are metal made, aluminum or steel with a precision machine that matches the item to produce. Once the mold has been created, the materials for the articles are fed into a heated barrel and mixed with a helical shaped screw.
This process requires careful design for shape and features for any item, the used materials, the properties and the molding machine. There are various considerations that need to be taken when injection molding process is applied.
EXTRUSION BLOW MOLDING (EBM)
Is one of the many blow molding methods for producing plastic bottles, jars and jugs. It’s a common technology used to process diverse plastics like HDPE, PVV, PC PP and PETG typically in bottles requiring multilayer technologies (With Special oxygen and moisture barrier requirements to improve product compatibility and stability).
EBM is the simplest type of blow molding. A hot tube of plastic material called a parison is dropped from an extruder that is captured in a water-cooled mold. Once the molds are closed, air is injected through the top or neck of the contains; Much like blowing up a balloon. When the hot material inflates and reaches the mold walls, the product freezes and the container help to maintain its rigid shape.
Extrusion Blowing Molding has several advantages, one of which is the lower mold costs compared to ISBM or IBM and the ability to form handles. Another advantage is the capacity to produce multiple layers, in some cases, bottles can have up to 7 layers of materials.
CAPS
In the case of the manufacture of caps with the help of a mold, the raw material is injected until it is full, then it is cooled to obtain the final shape of the cap.
