In plastic injection molding production, the mold type chosen often depends on the plastic part’s shape. At Seren Plastik, we help our clients pick the best plastic injection mold for their specific needs. This ensures that we produce high-quality injection molding results, offering excellent plastic parts at affordable prices. Our experienced team is here to support you every step of the way in your project.
What Types of Plastic Injection Molds Are There?
Plastic injection molding is a popular technique for producing large quantities of plastic components. In this process, molten plastic is injected into the plastic injection mold, and once cooled, the desired shape is achieved. The type of mold chosen for injection molding often hinges on the shape and characteristics of the plastic part. Here are some commonly used mold types in plastic injection molding production:
Basic Injection Molds
Among the various plastic injection molds, the basic injection mold stands out for its straightforward operation. This mold type is best suited for plastic parts with uncomplicated shapes. The mold has two primary halves:
- Cavity Side: This is the fixed section where the molten plastic is introduced.
- Core Side: This section is responsible for cooling, sealing the mold, and releasing the finished part.
Sliders in Plastic Injection Molds
For making plastic parts with special shapes, we use Plastic Injection Molds with Cores. These molds have parts that move. These moving parts help make shapes on the sides of the plastic item. If a plastic part needs bumps on the side or hollow spaces inside, these molds are a good choice.
Lifters in Plastic Injection Molds
Lifters in plastic injection molds have parts that move slightly when the mold opens and closes, usually at an angle of 5-7 degrees. These moving parts help make deep spots or bendy areas on the plastic item. If a plastic part has areas to grip or has a bent bottom, these molds are a good pick.
Plastic Injection Molds with Unscrewing Mechanism (Gearbox)
Plastic injection molds with unscrewing mechanisms have many gear parts that move together at the same time. These injection molds are often used to make plastic caps that are small or have sharp and thick twists. The gears inside the injection mold work by using a big gear or a special set of gears called a rack and pinion. Different methods can make these gears move.
