Low Pressure Overmolding Machine vs Traditional Molding: Which is Best?

Molding has become an essential part of the manufacturing industry. The process of molding includes melting a raw material into a specific shape, which eventually hardens into a solid product. There are different types of molding processes. However, two of the most widely used methods are low-pressure overmolding and traditional molding. Both of these processes have their benefits and drawbacks. In this article, we will discuss the differences and similarities between low-pressure overmolding and traditional molding, and determine which one is best.

Low-Pressure Overmolding.

Low-pressure overmolding is a molding process that is ideal for producing complex shapes and designs. The process involves injecting a low-pressure material, typically a thermoplastic polymer, around a pre-formed part. The low-pressure material is heated to a temperature high enough to melt the polymer to a liquid state. This liquid is then injected into the mold cavity where it surrounds the preformed part.

The low-pressure overmolding process is ideal for producing parts with intricate geometries, as it allows for more intricate designs. However, it is important to note that this process is time-consuming as it involves a two-step process.

Traditional Molding.

When it comes to traditional molding, the process involves melting a raw material and injecting it into a mold cavity. The mold is then cooled, the material solidifies, and the part is ejected from the mold. Traditional molding is often quicker than low-pressure overmolding as it involves a single-step process.

Traditional molding is the most popular and commonly used method for producing plastic parts. The process is well understood, and the equipment is readily available. However, the traditional molding process has limitations when it comes to producing complex, multi-layered parts.

Which is Best?

When it comes to determining which method is best, it ultimately depends on the requirements of the part. Low-pressure overmolding is ideal for producing complex shapes and designs, while traditional molding is ideal for simple parts that require a quick turnaround time.

Low-pressure overmolding is also suitable for producing parts that require multi-layering, which traditional molding cannot do. For applications requiring electronic applications, low-pressure overmolding is the perfect choice as it offers excellent protection for sensitive components.

Closing Thoughts.

Both low-pressure overmolding and traditional molding have their benefits and drawbacks. Each process has its own unique advantages, and the decision of which to use ultimately depends on the requirements of the part being produced. Regardless of which method is chosen, proper training and skill are required for optimal results.
