BLOW MOLDING & INJECTION MOLDING WHAT’S THE DIFFERENCE?


Blow molding and injection molding both are used to make singular like bottles and beakers injection molding solid parts then and plastic products etc. Injection molding process the plastic preform is injection molded and core the blow mold through and hot perform material off the core design blow molding.

Injection Blow Molding

The Blow molding process preform of hot hollow then parison of inflating closed mold its conforms that mold cavity, A blow-molded plastic bottles, can be produced plastic using process.


Blow Molding Materials


The blow molding raw materials that are utilized molding process of small pellets or granules, which is the first method called the parison and into a hollow tube, parts can be formed a wide range of materials.

1. Low-density polyethylene

2. Polyvinyl Chloride

3. High-Density Polyethylene

4. Polypropylene

5. Polyethylene Terephthalate

Injection Blow Molding Applications

Blow molding should be used to create numerous parts, The blow molding process is a plastic process thin and walled then hollow this product used are regularly and available also sizes and shapes few types of blow-molded parts including the process.

1. Tubs

2. oil jugs

3. Plastics drums

4. Shampoo bottles

5. Milk Containers

6. Storage tank

7. Water and soda bottles


Blow Molding Processes

The blow molding process of manufacturing that creates parts of plastic three types of unique process blow molded parts etc.

Stretch Blow Molding

This blow molding process two distinct stretch blow molding techniques conditioned to the proper temperature containers into blown production all in one continuous process. production rates are not a requirement this technics the most effective and best producing high volume carbonated bottles.

Injection Blow Molding

Little improvement in physical properties is realized next station and ejected blow molding allows the more detailed neck and finish area than extrusion blow molding then hot material core pin indexed blow molding station process very little orientation occurs.

Extrusion Blow Molding

Extrusion blow molding after the bottle cools and mold opens to eject the bottle and plastic is trimmed from the two halves of an open blow molding conservative of a parison or tube using a used for making plastic pipe begins with the conservative tube using die like those open pinching the bottom end closed.

Blow Molding vs Injection Molding

High quality, cost-effective plastic parts, and products blow molding and Injection molding two most popular ways to produce it should be a noticeable difference between parts made by injection molding parts creating solid parts, and hollow parts. If you are producing something that bottle caps and, hair combs, and computers and housings and television then if you are looking for products that are flexible, operational can hold a fluid like a bottle or a cooler molding is what you need.
