1. Determine Your Production Needs
Before choosing a machine, assess your production needs. How large are your parts? What&#;s your production volume? If you&#;re producing small, intricate parts, you might need a high-precision machine. Conversely, larger, less detailed parts may only require a basic machine. Production volume plays a major role in the type of machine you choose, so understanding your specific production requirements will help guide your decision.
2. Choose the Right Type of Injection Molding Machine
Hydraulic injection molding machines, electric injection molding machines, and hybrid injection molding machines each have their own unique advantages. Hydraulic machines are typically less expensive and highly versatile, making them suitable for high-tonnage applications. Electric injection molding machines offer precision and energy efficiency, though they come at a higher initial cost. Hybrid machines combine the benefits of both hydraulic and electric machines, offering a balance between energy efficiency and versatility.
-
Hydraulic machines are ideal for larger, less complex parts.
-
Electric machines are perfect for precision applications requiring high repeatability.
-
Hybrid machines offer a combination of both.
3. Focus on Energy Efficiency
Energy efficiency is a key factor in injection molding machine efficiency. Electric machines tend to be more energy-efficient than hydraulic machines. They consume less power during the molding cycle, which can translate into significant savings in energy costs over time. For high-volume operations, energy-efficient injection molding machines can lower operational costs and increase profitability.
4. Consider Machine Size and Clamping Force
Machine size and clamping force are crucial for ensuring you select a machine that can handle the size and complexity of your parts. The clamping force is the pressure the machine can exert to keep the mold closed during the injection process. Ensure the machine's size and clamping force align with the dimensions and complexity of your mold to avoid any production issues.
5. Assess the Machine's Precision and Repeatability
Consistency and precision are key in producing high-quality molded parts. Machines with higher precision and repeatability ensure that your parts come out exactly as designed, with minimal defects. For industries where tolerance is critical, such as medical or automotive, investing in machines that offer high precision is essential.
6. Evaluate the Cost of Ownership
The cost of ownership extends far beyond the initial price tag. When considering an injection molding machine, factor in the cost of maintenance, energy consumption, and potential repairs. While electric injection molding machines may have a higher upfront cost, their long-term savings in maintenance and energy consumption can make them a more cost-effective choice.
7. Check for Availability of Technical Support and Spare Parts
Choosing a machine from a manufacturer that offers strong technical support and readily available spare parts can save you time and money in the long run. Machines often require adjustments or repairs, so having quick access to support can minimize downtime and keep your production running smoothly. Always check the supplier&#;s reputation for providing after-sales support.
8. Look for Advanced Features and Technology
Modern injection molding technology offers a range of advanced features that can significantly improve your production process. Features such as automation, mold cooling systems, and real-time monitoring can enhance efficiency and part quality. Consider whether your machine will need additional features like mold cooling or robotic arms to fully automate your production line.
9. Consider the Machine's Lifespan and Reliability
Injection molding machine reliability and longevity are key factors in ensuring that your investment pays off over the years. Machines that are built for durability, with high-quality components, are less likely to break down, ensuring a longer lifespan. It's important to choose a machine that is known for its reliability, which will reduce maintenance costs and production interruptions.
10. Assess the Supplier's Reputation and Experience
A machine is only as good as the company behind it. Look for suppliers who have a strong reputation in the industry and a proven track record of delivering high-quality, reliable machines. An experienced supplier will not only provide a better product but also offer valuable guidance during the selection process and after-sales support.
Common Mistakes to Avoid When Choosing an Injection Molding Machine
When choosing an injection molding machine, it&#;s easy to make mistakes that could cost you in the long run. Avoid common errors such as:
The company is the world’s best energy-saving Bakelite injection moulding machine supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
-
Focusing solely on upfront cost instead of considering the total cost of ownership.

Moulders that want to reduce their energy bills must look at the entire process chain &#; from product design and machine technology to process control and production planning &#; to save money. ARBURG applications expert Lukas Krueger showed more than 100 attendees at ARBURG Ltd.&#;s open house in May, celebrating 100 years of the Hehl company, that adjustments covering eight steps of the entire moulding process can achieve savings of £ thousands per year, depending on the installed machine base and the measures taken.
All these key stages can produce energy savings for the moulder:
- Product design
- Mould technology
- Machine technology
- Peripheral technology
- Configuration
- Process integration
- Process control, and
- Production planning
Firstly, choose the right material, maintain tolerances suitable for plastics, and look to reduce wall thickness and material quantity. Then, energy can be saved by insulating the mould and clamping platens, tubes and even hot runners, if these are used. You can adjust the tube sizes and measure the energy consumption to find the most efficient tube size. Next, cooling in the mould can be modified to use water more effectively. An efficient design and close contours can reduce cooling time, cutting energy in the water pump.
Machine technology is the biggest single factor to reduce energy. Hybrid and all-electric machines are the most energy efficient, closely followed by energy-optimised hydraulic machines. Regular hydraulics, while robust and capable machines, can use twice the electricity of a modern electric machine. Insulate the cylinder heating zones, using full cylinder insulation if possible. When designing cylinder insulation, consider the optimum temperature regulation for your moulding process. ARBURG has run energy usage tests of fully insulated versus non-insulated cylinders and moulds, for different size machines. Energy savings depend on the electricity rate and machine size, varying from £240 to up to £2,280 for an ARBURG 820 S at 40p / kWh.
Using peripherals, the design and choice of temperature control units can also affect total energy usage. The configuration of the machine for different purposes and volumes will consume energy very differently. It depends on the machine technology; hydraulic, servo-hydraulic or electric.
High volume packaging typically requires a lot of energy due to the constant closing/injecting/opening, whereas low volume parts usually need more cooling time during which, with a servo-hydraulic machine, almost no energy is consumed (the pump idles during holding pressure). So, for packaging, an electric versus servo-hydraulic machine will register much higher energy-saving, but this difference is smaller for low volume work.
The relative energy gain per cycle (or energy saving per part) is higher on slow cycling parts. The energy gain per individual part is lower on fast cycling parts, but many more parts are produced per hour/day so the absolute energy gain over time is higher.
For process integration, automating operations can also reduce some energy used. Automation increases the machine&#;s productivity by having consistent operations on de-moulding or other secondary activities. This leads to reduced cycle times and reduce the overall time required for the machine to be used, cutting energy albeit in small amounts.
Although it may sound obvious, programming the optimum settings on the machine controller can reduce energy costs, sometimes very significantly. These settings include the mould locking force, dosing time, injection speed, the mould temperatures, and the cylinder and runner temperatures.
Here, arburgXworld Control FillAssist can help the user reduce rejected parts and create more stable production conditions (temperature, pressure, injection speed) that together produce the most efficient shot for the application. These settings are crucial &#; contact ARBURG to find ways to help you select the most energy-efficient settings that don&#;t affect performance.
Beyond the machine, peripherals and process settings, planning your production properly, considering energy management, can also save you money.
Typically, a commercial energy contract specifies in advance how much energy you need and what you&#;ll pay for. Exceeding the band can incur a higher kWh rate, so it is important to know your maximum peak load. The user can have an excess or higher capacity supply in place, but this facility will cost more even if it is not used. &#;It really pays to switch on all your machines in a sequence and having energy management on each machine to spread the electricity load over time,&#; says ARBURG Ltd. Sales Director Nicolas Stein.
Automatic and staggered switch-on: ARBURG&#;s software calculates the best moment during a start-up process each component is switched on, so everything reaches peak performance at the same time, just before starting production. Switching on all components together creates high peak loads and components can be heated up and ready to go while other areas need several more minutes to reach optimum temperature.
One very common problem for energy loss in plants is compressed air leaks. At 12 bar pressure, a 10mm diameter hole in the system can lose the company £640,000 a year at 40p p/kWh. Leak testing and repairing your air source will reduce energy bills. The message is to check every stage of the entire process chain for sub-optimal set-ups and amend them where possible.
