Cold runner systems come in two primary forms: two-plate and three-plate systems. The two-plate system is the simpler of the two; it uses a single parting line, allowing the plastic material to enter the mold on one side. While it has fewer moving parts, this system can only manufacture less complex plastic parts.

Deciding between a hot runner and a cold runner system is not a straightforward choice; it hinges on several factors. The type of product you intend to manufacture, your budget constraints, the materials you’re planning to use, and the scale of production are crucial variables influencing the decision. Choosing between hot and cold runners depends on your manufacturer’s capabilities, as top manufacturers like those listed in our China Mold Manufacturer article often have advanced technologies.

However, cold runner molds are not free from downsides. They produce more waste in the form of a solidified “sprue.” The slower cycle times could affect output rates, and the variety of moldable parts is somewhat limited. Balancing these pros and cons is key to choosing which system is the best fit for manufacturing requirements.

In the end, understanding your project’s unique requirements and the characteristics of your desired plastic parts is key to making an informed decision.

The cold runner’s disadvantage lies within the production of scrap, as the leftover plastic in the runner is ejected with the final product, producing waste resin. Additionally, utilizing a cold runner system might restrict the types of thermoplastics you can work with, particularly heat-sensitive polymers.

Choosing the right injection molding company means high-quality parts and fast production. This article looks at the top 10 plastic injection mold companies worldwide. Here are some of them:

The cost comparison of hot runner vs cold runner is reliant on several factors besides the upfront mold price. While cold runner systems are less expensive initially, their ongoing operational costs can increase due to slower cycle times and the need to recycle or dispose of the runner waste.

In the hot runner mold system, the plastic injection molding process results in no wasted resin, thus offering another form of efficiency: material use. Therefore, with hot runner molds, you can anticipate minimal material waste, effective use of energy, and quicker cycle times.

The hot runner vs cold runner debate is not new in the plastic components manufacturing industry. Each system has its unique range of advantages, disadvantages, and best choice of materials. The primary difference between these two systems lies in the pathway, or runner, whereby the molten thermoplastic travels from the heating cylinder to the individual molding cavities. Understanding the basics of injection moulding is key to choosing the right runner system, which is why we recommend reading our Injection Moulding Parts Basics for foundational knowledge.

However, it’s not just about speed. The hot runner approach is also about efficiency. The molten material travels straight from the heating cylinder to the mold cavities without leaving any scrap, fundamentally different from the cold runner system.
