Practical notes on injection molds, blow molds and recycled granules: how to prepare a drawing, what drives the cost, what to look at when buying.

    How to prepare a drawing for an injection mold quote

    To quote an injection mold we need a 3D model or a drawing of the part, its material and the planned volume. The more precise the data, the faster and more accurate the estimate of cost and lead time. Below is what exactly to prepare and how to avoid extra back-and-forth.

    What drives the cost of an injection mold

    The cost of an injection mold depends on the size and complexity of the part, the number of cavities, the steel and its heat treatment, the runner system, surface and accuracy requirements, and the tool life you need. Below is how each factor affects the price and where you can save without losing quality.

    Recycled plastic granules: how they differ from virgin

    Recycled granules are plastic reprocessed from production waste or used products. They cost less than virgin material, but their properties depend on the feedstock and processing, so for each task you need to know the polymer, the melt flow index and the colour. Below is where they fit and what to check before buying.
