One article teaches you to quickly understand cold runner vs. hot runner, choose the right mold and save a lot of money

Still confused about the difference between cold runner and hot runner? Fanstar injection mold manufacturer, with 20 years of experience, tells you: Choose the right runner and reduce costs by 30% immediately!

Cold runner mold - An economical "old ox"

It features a simple structure and low cost, making it suitable for "cost-performance" projects with an order volume of no more than 100,000 times. The drawback is that the water outlet has to be cut off for each beer. The weight of the feed head is approximately 3% of the product's total weight, and the waste of raw materials is obvious to the naked eye. The cycle is also slow, and the gate marks need to be reprocessed. If your product has a high grammage and your order is not urgent, the cold runner is the "money-saving expert".

Hot runner molds - High-capacity "Money Printing machines"

Through a constant-temperature heating rod and a timing valve needle, the molten material is directly delivered to the cavity, with zero sprue and zero waste. The cycle is 30% faster, and the monthly production capacity can be easily doubled. It is especially suitable for orders of "high appearance + high output" in precision electronics, medical, cosmetic packaging and other fields. Although the initial investment is 1.5 times higher, it can break even with 200,000 mass productions. The more you use it, the more you earn!

How to choose? Look at three points

Output: ≥ 200,000 times. Select the hot runner with your eyes closed.

Materials: High-priced materials such as PC, PMMA, flame-retardant ABS, etc. The hot runner saves materials and is more cost-effective.

Appearance: Transparent and mirror-finish parts, beautiful without pouring.
