- Insulating the Barrel.
- 100\% Electric Machines.
- Use a Variable Speed Drive.
- Calculating Life Cycle Costs.
- Use the Correct Machine for the Product.
- Leverage Automation to Optimize Cycle Times.
- Final Word.
How much electricity does an injection molding machine use?
A typical injection molding plant (Fig. 1) will have a process load in the region of 0.9 to 1.6 kwh/kg (0.4-0.73 kwh/lb).
How do you calculate energy consumption on an injection molding machine?
Finally, the total energy consumption in kilojoules per part is computed by multiplying the power consumed by the machine in each stage of molding, and then multiplying it by the estimated part-specific setup and cycle times.
How do you reduce flow in injection molding?
Here are some common remedies for flow lines in injection-molded products:
- Increase the injection speed, pressure and material temperature to ensure the material fills the mold before cooling.
- Round the corners of the mold where wall thickness increases to help keep flow rate consistent and prevent flow lines.
What is electric injection Moulding machine?
Electric Plastic Injection Molding These machines are powered by digitally controlled high-speed servo motors rather than hydraulics, allowing for a faster, repeatable, more precise, and energy-efficient operation.
What is hybrid injection molding machine?
A New Kind of Hydraulic-Electric Hybrid Unlike the typical hybrid, a new electric-based hybrid injection molding machine for the first time delivers electric efficiency along with hydraulic force. The new system uses a hydraulic accumulator to provide the force that would otherwise require an all-hydraulic machine.
How can I reduce my flow mark?
How to Prevent Flow Lines
- Increase the injection speed, pressure, or material temperature: Slow-moving molten plastic is more likely to cool quickly and cause flow lines.
- Round the corners of the mold where wall thickness increases: This helps keep flow rate consistent to the thicker sections and prevents flow lines.
What are the merit of all electric injection molding?
Ideal for cleanroom production – no leakage of oil. Cost savings over the time of production – lower operation costs due to energy savings, less consumable expenses like oil filter change, lower unit costs and less material costs. Typically higher injection speeds (up to 800 mm/sec) and even faster clamp motion.
What is hydraulic molding machine?
Hydraulic Plastic Injection Molding. These types of machines employ hydraulic cylinders to clamp together two halves of a mold at high pressure. Plastic substrate pellets are then melted, and the liquid is injected into the mold cavity.
How do you prevent injection molding from shrinking?
Decreasing shrinkage – If you desire a decreased shrink rate, add cooling time in the injection mold, lower the mold surface temperature, decrease component wall thickness, decrease the resin melt temperature during injection, increase resin injection speed, and increase packing density or holding pressure.
Can plastic injection molding reduce electricity costs on hydraulic machines?
The fact is, it easy for an injection molder to reduce electricity costs on existing hydraulic machines just by adjusting parameters in the plastic injection molding process. The ability to reduce costs without having to invest in expensive new technology machines is totally in your control.
How can I reduce injection molding price per piece cost?
It sounds simple, but one of the easiest ways to reduce price-per-piece cost in injection molding is by increasing part quantity. That is because the initial upfront cost to design and machine the mold amortizes over more parts.
How to design injection molding design considerations to stretch manufacturing dollar?
Here are 11 injection molding design considerations to stretch your manufacturing dollar: 1. Eliminate undercuts 2. Get rid of unnecessary features 3. Use a core cavity approach 4. Reduce cosmetic finishes and appearances 5. Design self-mating parts 6. Modify and reuse molds 7. Pay attention to DFM analysis 8. Use a multi-cavity or family mold 9.
What are the process parameters in plastic injection molding?
An important part of the plastic injection molding process are the process parameter settings such as hold time and screw plasticizing time. Process parameters give direct control over part quality and cycle time.
