Injection Molding Machine Selection Guide: How to choose the right injection molding machine model to meet your production needs
In today’s rapidly developing manufacturing industry, injection molding machine is the core equipment for the production of plastic products, and its selection has a crucial impact on production efficiency, product quality and even the economic benefits of enterprises. The correct choice of injection molding machine model not only improves production capacity, but also ensures maximum return on investment. This paper aims to provide a scientific, rigorous and easy to understand injection molding machine selection guide to help manufacturers quickly find the most suitable injection molding machine model according to the actual production needs.
First of all, we need to understand the basic information and working principle of the injection molding machine.
Injection molding machine is mainly composed of injection system, closing system, hydraulic transmission system, electrical control system, lubrication system, heating/cooling system, safety monitoring system and so on. It heats granular or powdered plastic raw materials to a certain temperature, melts them, injects them into the mold cavity under the push of the screw, and forms the required plastic products after cooling and curing.
Next, we explore how to choose the right injection molding machine model according to the production needs:
Determine product requirements: Specify the type, size, accuracy and material characteristics of the plastic products to be produced. This will directly affect the choice of injection molding machine, such as the production of precision electronic components may require high-precision injection molding machines, and large plastic parts may require large tonnage machines.
Calculate the clamping force:The clamping force refers to the maximum force that the injection molding machine can withstand when it closes the mold, and it must be greater than the pressure generated by the plastic melt during the injection process. According to the projected area of the product and the fluidity of the plastic used, the minimum clamping force required can be calculated.
Evaluation of injection volume: Injection volume refers to the amount of plastic melt that the injection molding machine can inject at one time, usually in grams (g) or cubic centimeters (cm³). When selecting an injection molding machine, it should be ensured that the maximum injection volume can meet the needs of the product, and taking into account the production efficiency, it is not appropriate to choose too large a model.
Consider the mold size: the size of the mold determines the opening stroke of the injection molding machine and the workbench area. Ensure that the table of the selected injection molding machine can accommodate the mold and that the opening stroke is sufficient to complete the release of the product.
Analysis of the production cycle: The production cycle refers to the entire time from the beginning of the injection to the product molding and taking out. When selecting an injection molding machine, it should consider whether its cycle time matches the production demand to improve production efficiency.
Consider energy efficiency: Modern injection molding machine designs are increasingly focused on energy efficiency. Choosing an injection molding machine with energy-saving characteristics, such as a servo motor drive system, can significantly reduce energy consumption and reduce production costs.
Budget and cost-benefit analysis: In the premise of meeting the technical requirements, it is also necessary to consider the investment cost of equipment and long-term operating costs. Carry out cost-benefit analysis to ensure that the selected injection molding machine can bring good return on investment for the enterprise.
After-sales service and technical support: The selection of injection molding machine suppliers with good after-sales service and technical support can be quickly solved when the machine fails to reduce the risk of production disruption.
To sum up
Choosing the right injection molding machine model is a process involving many considerations. Manufacturers need to according to their own production needs, comprehensive consideration of product characteristics, clamping force, injection volume, mold size, production cycle, energy efficiency, budget and after-sales service and other factors, in order to select the most suitable injection molding machine model. Through scientific and rigorous analysis and evaluation, combined with professional knowledge and experience, manufacturers can ensure that the injection molding machine investment can meet the current production needs, and has the flexibility and scalability to adapt to future market changes. Such a selection process not only reflects a positive attitude, but also in line with the pursuit of efficient, energy saving, environmental protection of modern manufacturing values.
