Introduction
Do you want to produce top quality plastic components with high precision, repeatability and on a large scale? The answer is injection molding machining. This potent process shapes the foundation of modern plastics parts and drives countless applications from complex medical devices to rugged automotive parts. It’s essential to understand the finer details of injection molding machining — the process of choosing, operating, and maintaining the machines themselves — to maximize their potential.
Over the years, at Daoben Machinery, we have made it our mission to supply manufacturers with the best in the market injection molding machines, with clamping force from 30 tons to a staggering 4000 tons. In this article, we will explore the benefits and considerations of injection molding machining and how the right machine can revolutionize your production process. Our primary focus will be on actionable insights that empower you to make better-informed choices, regardless if you’re building on top of what you have or embarking on a new venture. It’s really not just about selling machines; it’s about offering solutions.
What is Injection Molding Machining?
The injection molding machining process is the entire process, centered around the actual injection molding machine itself. That includes not just the molding process (in which molten plastic is injected into a mold) but the selection, operation, maintenance, and optimization of the machines that enable it. It’s understanding the interplay of:
Clamping force:
The force applied to keep the mold shut during the injection process. If the clamping force is not strong enough then flashing (excess plastic comes out) occurs. Diverse range of clamping force: machines with a table designed for small molds up to a huge clamping force, accordingly wide range of clamping force is offered by Daoben Machinery.
In the injection unit, plastic granules are melted down and injected into the Mould. Important parameters are injection pressure, injection speed, and screw design.
Control System:
This is the “brain” of the machine, controlling temperature, pressure, timing, and other critical parameters. Modern machines (for example, those from Daoben Machinery) have advanced, easy-to-use control systems that create results that can be repeated with precision.
Mold Design and Construction A separate process in itself, mold design and quality are closely tied to the successfulness of injection molding machining. It should be able to deal with the size and weight of the mold as well as the cooling capacity.
Considerations on Material Choice:
There are multiple types of plastic material, each with a range of melting point, viscosity, and shrinkage. For the material you choose, the injection molding machine will need to be configured.
Understanding these factors is crucial to obtain the best possible results in both part quality and cycle time, and the efficiency of the overall process.
The Benefits of Injection Molding Machining
Revolutionizing Your Plastic Part Production with Injection Molding Machining The benefits are many and persuasive:
High Precision & Repeatability:
Injection molding enables you to produce extremely complex parts to tight tolerances. Companies can then quickly scale using the machine to make thousands or even millions of identical parts with minimal variation once the process has been optimized. This is critical for applications demanding consistency, particularly within the medical, automotive, and electronics sectors.
Mass production:
Injection molding is suitable for high volume production. Cycle times can be extremely fast, enabling the quick production of huge amounts of components. This scalability allows this solution to be very affordable for high-demand products.
Material Versatility:
Injection molding can be used with a variety of thermoplastic and thermoset materials, including:
- Polypropylene (PP)
- Polyethylene (PE)
- Acrylonitrile Butadiene Styrene (ABS)
- Polycarbonate (PC)
- Nylon (PA)
And many more! This variability enables manufacturers to choose the material best for the part’s application — strength, flexibility, chemical resistance and cost are all factors that can be considered.
Design Flexibility:
Injection molding can create complex geometries and intricate details, which would be difficult or impossible/intended with other manufacturing methods. Uninterrupted features like undercuts and threads and thin walls can be built right into the mold.
Cost-effectiveness (at scale):
Injection molding machining and molds are expensive to purchase, but the per-part cost is extraordinarily low at high volume. If you’re looking for rapid manufacturing with minimal material waste, that’s another cost argument for mass production.
Lowered Material Waste:
Injection molding creates little waste in comparison to subtractive manufacturing processes (such as machining from a solid block). A precisely measured amount of material is injected into the mold.
Key Considerations When Choosing an Injection Molding Machine
Selecting the right injection molding machine is a critical decision that will impact your production capabilities for years to come. Here are the key factors to consider:
Clamping Force:
As mentioned earlier, this is the force required to keep the mold closed during injection. The required clamping force depends on the projected area of the molded part and the injection pressure. Daoben Machinery’s range (30-4000 tons) ensures we have a machine to fit your specific needs. Our experts can help you calculate the precise clamping force required for your application.
- ClampingForce(tons)=(ProjectedArea(in2)∗InjectionPressure(psi))/2000ClampingForce(tons)=(ProjectedArea(in2)∗InjectionPressure(psi))/2000
- Note: This is a simplified formula; other factors can influence the required clamping force.
Shot Size:
This refers to the maximum volume of plastic the Injection molding machining can inject in a single cycle. It’s crucial to choose a machine with a shot size that’s appropriate for your part size. Too small, and you won’t be able to fill the mold; too large, and you’ll waste material and energy.
Screw Design:
The screw is responsible for melting and conveying the plastic. Different screw designs are optimized for different materials and processing requirements. Daoben Machinery offers various screw options to ensure optimal performance with your chosen materials.
Control System:
A modern, user-friendly control system is essential for precise control over the injection molding process. Look for features like:
- Real-time monitoring of key parameters (temperature, pressure, speed)
- Programmable injection profiles
- Fault diagnostics
- Data logging for quality control
- Connectivity for remote monitoring and control
Energy Efficiency:
Injection molding machines can consume significant amounts of energy. Choosing an energy-efficient machine, like those offered by Daoben Machinery, can significantly reduce your operating costs and environmental impact. Look for features like servo-driven pumps and optimized heating systems.

FAQ’s
Injection molds are machined using CNC milling, EDM (Electrical Discharge Machining), and grinding for precision shaping and detailing.
The four stages are clamping, injection, cooling, and ejection.
Injection molding produces parts by injecting molten material into a mold, while machining removes material from a solid block to shape the part.
Some injection molding machines have CNC controls for automation, but they are different from CNC machining centers used for cutting operations.
