Packaging is a part of daily activity! Bottles, containers for drinks, foods, medicines and more fill recycling bins and our pantry shelves. Thin and walled plastic bottles are made with a process called blow molding, and where air is blasted to a metal mold that was calibrated on a scale, and the waiting thermoplastic assumes the form of the mold. On account of pressure and the heat inherent in the blow molding process, metal molds that are machined are required by large scale manufacturing.
Nevertheless, the molds can, in fact, be 3D printed with PolyJet. A provider of these sorts of bundles, please Precision Plastics, engineers and designs every kind for a wide selection of customer applications and businesses. Lately, a Plasel client needed to prototype a brand new package design to make sure it’d fit with an automated conveying system. Stratasys 3D printing technologies to make a blow mold was utilized by places. Selecting 3D printing over machining for these prototypes provided savings of money and time compared with conventional machining methods for blow-molded prototypes. The 3D blow molds that were printed allowed this scale manufacturing run to occur in two days.
Stratasys 3D molded blow molds were perfect for producing the prototypes our customers needed to receive their product clarified a research and development director at Plasel, Nir Hadar. To recap, 3D molded blow molds provide a quick procedure for project validation before metal molds are processed for big runs. Modifications to layouts including claps, snaps, and hinges may be easily and inexpensively made, and all these prototypes may be utilized to check form, fit and function. Please Comparison of Stratasys PolyJet 3D Printed Molds using Conventional Metal Molds – Method – Production Time – Cost – CNC Machining – Up to 20 days – $5, 000 – Aluminum Mold – Up to 20 days – $5, 000 – PolyJet Mold – 2 days – $280 – Savings – 18 days – $4, 720 – For 100 finished parts – For much more on with 3D printing in the blow molding manufacturing process, watch our video! – This blog post is part of our Toolless Tools Without Tooling, where we’re exploring the advantages of 3D printing in the production industry.
