Insert molds and Free standing molds

Plastic injection molding is the process used to produce low or high volumes of custom plastic parts for commercial and industrial use. From intricate automobile safety components to simple products like business card holders, the applications span a range of industries.

In combination with skilled mold designers, software technology, and the use of expensive CNC machinery, MOLDEPLASTICO builds molds for plastic injection that are used to produce high quality molded plastic parts. Our injection molding experts look forward to working with you on your mold build project as the next step toward manufacturing your custom molded parts.

Molds For Plastic Injection

Receiving high-quality plastic parts starts with buying a quality built mold. We’ll work with you every step of the way to ensure you’re familiar with the different types of molds for plastic injection that are available, and we’ll make sure you’re completely informed before you buy. Below we provide you with a valuable understanding of basic injection mold construction types and the benefits of each.

Insert molds have a cavity side and core side insert that fit inside of a custom mold base here at MOLDEPLASTICO. They are a great way for us to offer customers economical tooling at very rapid lead times. The insert style design is great for small and medium size parts that require low quantity part orders or fast delivery of parts.

Even though insert molds are low cost in basic design, they are made with the same high quality materials and components as free standing plastic injection molds and provide the same high quality defect free parts.

Low cost

Average lead times from 5 to 15 days

Good for small parts

Good for 1 cavity molds and small order quantities

What is insert moulding?

Insert moulding involves injecting plastic in a mould onto a component made from a different material. This component is called the insert. It is often made from steel or some other type of metal. The advantage of this technique is that the insert is entirely covered by the injected plastic, and thus optimally integrated. You might think that placing the inserts inside the injection-moulding machine takes a lot of time, but that is not the case. At Rompa Group, this process is fully automated.

Free standing molds, also known as stand-alone molds, provide an all-in-one design. They are built to include the mold base, inserts, and all components needed to be fully functional alone.

A properly designed free-standing mold is built for production inside any SPI standard injection molding machine that is sized properly for the mold. Stand-alone molds have a higher cost, but they are a good choice for multi-cavity production and with high-quantity orders.

A summary of free-standing molds for plastic injection includes:

Higher cost

Average lead times of 3 to 8 weeks

Best method for parts that will not fit into insert molds

Best choice for multi-cavity molds to reduce part cost
