Was ist Kunststoff-Spritzgießen?

Plastic injection molding is melting thermosetting/thermoplastic plastic pellets, which are then injected under pressure into a mold cavity where they fill and solidify to create the finished product. Injection molding is used to create a vast range of items, each with a unique size, level of intricacy, and use. A mold, raw plastic material, and an injection molding machine are required for the injection molding process. In the injection molding machine, the plastic is melted and then injected into the mold, which cools and solidifies to form the finished object. The following section goes into further information about each step of this process.


The four stages of the injection molding process cycle, which lasts from a few seconds to two minutes , are as follows:


The clamping unit must first firmly close the two mold halves before the material can be injected into the mold. One half of the mold is let slide while the other halves are each coupled to the injection molding machine. The clamping unit is hydraulically operated and forces the mold halves together with witcoupledforce to maintain the mold shut while the material is injected. Depending on the machine, larger machines (those with more substantial clamping pressures) will take longer to seal and clamp the mold. The machine’s dry cycle time can be used to estimate this period.


The raw plastic material is fed into the injection molding machine and moved toward the mold by the injection unit, typically in the form of pellets. The material gets melted during this procedure due to pressure and heat. The fast-injected molten plastic mould packs and holds the material due to the pressure rise in the mold. The shot is the term used to describe the volume of substance injected. Due to the complicated and erratic flow of molten plastic into the mold, it is challenging to determine the injection time precisely. The shot volume, injection pressure, and power can be used to predict the injection time.


As soon as the molten plastic inside the mold makes contact with the internal mold surfaces, it starts to cool. The plastic will harden into the desired part’s shape as it cools. The portion could, however, experience some shrinkage during cooling. During the injection stage, the material is packed to prevent visible shrinkage and allow more material to flow into the mold. Unable to be opened until the required cooling period has passed is the mold. Several thermodynamic characteristics of the plastic and the maximum wall thickness of the part can be used to predict the cooling time.


The ejection mechanism, which is attached to the back half of the mold, can expel the cooled item from the mold once enough time has passed. A device is utilized to force the part out of the mold when opened. Because the object shrinks and sticks to the mold during cooling, it must use force to remove it from the mold. Before the injection of the material, a mold release agent can be sprayed over the surfaces of the mold cavity to make it easier to eject parts. The machine’s dry cycle time can be used to estimate the amount needed to open the mold and remove the component, which should also account for the time it takes for the part to release itself from the mold. The mold can be clamped shut so the subsequent injection can occur after the amount has been extracted.

Following the injection molding cycle, post-processing is frequently necessary. The substance in the mold’s channels will harden while still being bonded to the part during cooling. Removing this extra material and any flash from the piece is essential, usually using cutters. For some materials, such as thermoplastics, you can recycle the leftover trimmings by being fed into a plastic grinder, also known as a regrind machine or granulate, which turns the leftover trimmings into pellets. Regrind must be blended with raw material in the correct regrind ratio due to some degradation of the material’s characteristics to be reused in the injection molding process.


Before starting an injection molding project, keep the following in mind:


Given the price of the equipment and mold’s price, the entry cost for manufacturing with injection molding might be high.

Production Quantity

Knowing how many components you wish to produce is crucial to assess whether injection molding is the most economical production process.

Design Factors

Injection molding will be simpler if your products have fewer pieces and a simpler geometry. The plastic mould design is also crucial to avoid production problems.

Production Considerations

Utilizing machines with hot runner molds and well-planned tooling will help production and reduce cycle time. You can produce parts more cheaply by making these little adjustments and using hot runner systems. Reduced assembly requirements will also result in cost savings, mainly if you have thousands or millions of pieces.


There are numerous variations in the injection molding process, including:

Compression Molding

In some ways, compression molding is the antithesis of injection molding. The mold is filled with molten plastic, which is then sealed. Somewhere in the mold is an intake hole via which another device applies pressure. The final shape is achieved when pressure drives the plastic outward into the mold’s hollow interior. Items created via compression molding frequently include a lot of “flashing” or extra plastic, which needs to be removed. Rubber products can also be made using compression molding.

Transfer Molding

Similar to compression molding, transfer molding applies pressure using a metal plunger. The molten substance is put inside the mold and sealed there. The material is forced to expand outwards and fill in the geometry of the mold by a metal plunger, which resembles a big shaft and is shoved deep into the mold. Rubber or polymers can both be used for transfer molding.


Extraction is a few molding techniques used on hot or cold materials. A die is utilized during extrusion processes as opposed to a three-dimensional mold. A die is called a die when a material is forced or extruded through a two-dimensional hole with a specific geometry. The extruded substance—typically a metal like aluminium or plastic—takes on the geometry of the die. At the same time, multiple pieces of the same size are produced by semi-continuous extrusion, and very long sections are made by continuous extrusion.

Blow Molding

Compression molding is similar to blow molding, except the former uses compressed gas to force the plastic into the shape of the mold. Plastic is melted and sealed inside a mold. The pressurized gas is pushed into a tiny hole in the closed mold. Even though the gas condenses, it finally generates enough external pressure for the plastic to fill the geometry of the mold.

Rotational Molding

Rotational motion is used in rotational molding to control the required pressure to fill the mold. A mold is filled with molten plastic and sealed. The mold then rotates, allowing the molten plastic to fill in all the cracks and patterns of the cast by dripping down the sides.


The hydroforming metal-specific molding process employs water pressure to press metal into a dye or mold. The metal is enclosed inside the mold or dyeing apparatus after being heated to a malleable but not molten state. It can pump in high hydraulic water through a small hole. The metal is forced to fill the geometry of the cast by the intense pressure of the water in the mold. The workpiece is then ejected after the water has been drained. Explosive hydroforming is a subtype of hydroforming that uses explosives. In this technique, the detonation of a small explosive exerts pressure on the water. The water is forced into the metal by the sudden pressure of the outwardly moving explosion, and the metal is then forced into the mold geometry.


Laminating is a straightforward form of plastic molding that involves applying pressure to a laminated plastic sheet to a substrate. The laminate will occasionally overhang the substrate, forcing a second laminate sheet from the opposite side to adhere to the first sheet. Heat or physical pressure from a block is used to bind the plastic to the substrate.


The top 7 elements that you should take into account while selecting a plastic injection molding firm are as follows:

1. Excellent design team

Design is one of the most crucial components of a plastic molded object. A great design team at the plastic injection molding firm you choose will go a long way toward assuring the desired outcome.

A plastic injection molding firm that offers a one-stop shop will assist you in producing the products you want while meeting your schedule and financial requirements.

4. Products & Services

The product application should be considered when selecting a plastic injection molding business. The part’s intended purpose is crucial when considering different manufacturing, processes, including design, development, and production. You should be able to get advice from an injection molding company on the best plastic resin to use for various product applications.

Various plastic resins’ strength, moldability, flexibility, durability, heat resistance, etc., varies. Metals are currently being replaced by plastic in multiple industries to lighten products and cut costs. Based on the final usage of the product and your budget, your chosen plastic injection molding firm should be able to advise you on the best plastic resins.

5. Specification Requirements and Technical Feasibility

Manufacturers of goods frequently wind up compromising on the requirements for a product. But if you collaborate with a reputable company for plastic injection molding, you may get your components made regardless of the conditions.
Based on the requirements for a plastic product, a reputable plastic injection molding firm should be able to advise you and offer appropriate options. And none of the specifics should be compromised for this to happen.
