Intex specializes in producing extraordinarily small plastic parts that require extreme precision. We also produce small-size parts with micro features, mould in and around existing components, and create components using intricate lead frames or inserts.
Areas of Expertise
High Precision / Complex Moulds
High/Low Production Volume Moulds
A low cavity mould will have a shorter lead time and they are comparatively inexpensive, but in the end there will be a higher price per piece. This is generally most appropriate when the production quantities are low or for prototype moulds.
Going with a high cavitation mould will be more expensive at the onset, but the resulting price per piece will be lower due to economies of scale. This becomes more and more appropriate with higher production quantities.
Complex Valve Gate Multi-Cavity Tooling
Conventional valve-gated hot-runner systems have a tough time handling these challenges. Opening and closing all the valve gates at the same time necessarily limits the degree of control over weld or knit lines, gas traps, localized packing, and unbalanced flow. Fortunately, there is a technique that provides almost unlimited control over which parts of a tool fill when and how fast. It’s called sequential valve gating, or SVG. Adding a programmed time sequence to the opening and closing of valve gates is not new technology, but moulders are gradually gaining appreciation of its problem-solving prowess.
Multi-shot (Pick & Place / Rotary) Moulds
Multi-shot (or two-shot) moulding is the process of physically bonding two different materials into one component within one manufacturing process. A proven technology that is used across many industries, multi-shot moulding allows multiple materials to be injected into separate locations on the same mould. Different surfaces, even incompatible materials, can be securely bonded into a single component that is stronger and more durable than its two-piece counterpart.
Complex Aluminum Prototype Moulds
In other cases, aluminum tools are designed such that potential changes can still be made during the development process (e.g. if prototype iterations are to be made during injection moulding). In general, aluminum tools are easier to machine than steel tooling, and so iterative design changes are typically less burdensome.
Multi-material moulding is a common way of forming products that require characteristics one material alone just can’t provide. It’s often used to give added aesthetic appeal, stability, functionality, or marketability over traditional designs. Common examples include automotive taillights, toothbrush handle grips, seals, gaskets, and a variety of other products.
The unique needs of each application usually drive demand for multi-material parts, and moulders have many options for production techniques. Since each multi-material application is unique, there’s no standard best method for success. Each moulding solution must be tailored to meet the needs of the final product.
