description: "Injecting is a slower process compare to the other machines, generally it takes from 10 to 15 min to inject a product. That's why we've been looking for different alternatives to make this process as fast as possible, even for very simple steps like opening and closing. When you inject 3-5 times is not that bad to screw in and out 4-6 bolts, but when you need to do the same step 50 times, to save a couple of seconds each time, it's a lot! "

  - text: "Before you start, gather the materials and tools you need to make the quick release system:\n\nMaterials: 4 bike skewers (standard thread thickness: 5mm).\nYou can use more depending on the type of mould you have, i would recommend you to use at least 4. \n\nTools: ruler, M5 die, safety glasses, marker.\nAnd for cutting and sanding, you can either use. a hand saw, file adna sanding paper or a grinder with cutting and sanding disc\n"

This is how much you need to cut off to fit the mould thickness, so you can tighten it up properly. \n"
