Molding Press Machine

Molding Press Machine

I always thought that some of the exact customized plastic, wood, and steel products were carved by hand. Little did I know that they were made using Molding press machines! In case you’re in dire need of a product that can get you the exact shape, form, and quality you’re looking for, a Molding press machine might just be what you’re looking for.

In this article, we’ll discuss what a Molding press machine is, what you can use it for, how you can use it to benefit your business, and, of course, where you can get a world-class quality machine like it!

What is a Molding Press Machine?

In case you weren’t aware, a molding press machine, which is often known as an injection press, is a machine used for the injection molding of plastic items.

Molding press machines consist of two major components: an injection unit and a clamping unit. These are what classifies a machine as a molding press machine instead of just being a standard type of press.

In conclusion, this machine is designed and made to maintain the mold closed during operation and to ensure that all results and finished products are of accuracy and high quality.

What Are the Different Types of Molding Press Machine?

In case you didn’t know, there are actually a few different types of molding presses currently being used by organizations. These presses are:

Compression Molding

Compression molding is somewhat the opposite of injection molding. Molten plastic is filled into a mold which is then closed. It’s the process where pressure is applied through an intake hole in the mold, forcing the plastic to take the shape of the mold’s interior.

Transfer Molding

Transfer molding resembles compression molding but uses a metal plunger to apply pressure. The molten substance is sealed within the mold, and a metal plunger forces it to expand and fill the mold’s geometry.

Thermoforming Molding

Thermoforming is a process where thin sheets of thermoset or thermoplastic plastic are molded using a vacuum. The plastic sheet is heated until malleable, placed over a mold, and then drawn into the mold using a vacuum.

The excess plastic is trimmed off, and the molded plastic is removed from the mold.

Injection Molding

Injection molding uses plastic pellets from High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Polyethylene Terephthalate (PET) as raw materials. The resins are melted and then injected into a clamped mold through a nozzle.

The mold is cooled to help the molten plastic set, and once set, the mold opens to release the precisely shaped plastic.

Vacuum Molding

Vacuum forming, a type of thermoforming, is typically used with thin plastic sheets or “film”. The film is stretched over a mold and then suctioned around it using a vacuum.

Rotational Molding

Also commonly referred to as rotomolding, is a casting technique that creates hollow objects without the use of pressure.

Instead, rotational motion is used to distribute the molten plastic within a sealed mold. It’s one of the rarest types of molding.

Hydroforming

It is a molding process specific to metals, where water pressure is used to shape malleable metal within a mold or die. There are two types of hydroforming: sheet hydroforming and tube hydroforming.

Blow Molding

Blow molding uses PET preform, created by injection molding machines, as raw material for manufacturing plastic bottles. The PET preform is heated, placed into a mold, and then stretched and inflated to take the shape of the mold.

Extrusion Molding

Lastly, extrusion molding. It is a process that can be used on both hot and cold materials. It uses a die, a two-dimensional hole with a specific shape, through which material is pressed or extruded.

The extruded material takes on the shape of the die.

These are the different types and classifications of molding press machines. Take note, these are not all. You will be able to find others that are either less specific to an industry or more directed towards a particular business sector.

Dissecting an Injection Molding Press Machine

Molding press machines or injection molding presses are made and comprised of a few different common components and parts. These parts, when applied to a whole, become lethal machines and equipment you can use to produce premium-quality plastics, woods, and steels.

Here’s a list of the different components and parts of an injection molding press:

  • Hopper:The part where the plastic material is introduced before the injection molding process starts. It’s like the input of a press machine.
  • Heater: A heating element can be mounted to the barrel and used to melt the molding material in the hopper, resulting in liquified material.
  • Barrel:Also called the material tube and barrel, melts the plastic material, allowing it to flow through the barrel. The screw within the clamping unit injects plastic into molds or cavities.
  • Clamping Component:The clamping unit’s functions include opening and closing an injection mold and ejecting injection-molded goods. The hydraulic and toggle designs are the two major types of clamping systems.
  • Injection Unit:The aim of the injection unit is to dissolve the raw material and steer it into the mold. The injection unit comprises of the hopper, the barrel, and the screw. The polymer granules are dried and placed in the hopper before being blended with the coloring pigment or other strengthening ingredients. 
  • Nozzle:The nozzle is an injection molding element placed at the machine’s ejector system’s bottom. It forces liquified plastic from the barrel into the mold.
  • Ejector Pins:Ejector pins are essential for making components. They are an important part of the ejection mechanism in molds, which impacts the result of goods in the injection molding process.

These are among the most common parts and components of a molding press machine or an injection molding press.

Molding Press Machine Price

A molding press machine’s price varies substantially based on its size, capabilities, and condition.

Large industrial injection molding equipment can be between $50,000 and $200,000+. For operation, maintenance, and monitoring, these machines require professional and expert labor.

On the other side, you may find secondhand compression molding equipment for as little as $8,7502.

If you’re searching for anything special, such as a Rubber Mat/Carpet/Cushion Compression Molding Press Machine, expect to pay between $10,000 and $34,5003.

What Are the Advantages of Press Molding

Molding press machines carry a too few different benefits and advantages. In case you’re interested in finding them out, here’s a few of the main ones that the have to offer:

  • The fundamental advantage of this method is that complicated forms with thin walls (5-15 mm) may be readily molded and withdrawn from the die without damage/harm/deformation.
  • Injection molded parts offer a high degree of dimensional tolerance.
  • The main advantage of this approach is that it produces relatively little scrap in comparison to other techniques.
  • those produced by injection molding compete with those produced by investment casting and sophisticated machining.
  • When compared to other procedures, this process has a high output rate.
