The success of your injection part begins with choosing the right plastic, even before the mold. The wrong material = a part that breaks, flexes, wears out or is needlessly expensive. This guide compares the five main thermoplastics MARG works with — ABS, PP, PE, POM, PA — by function and answers the question “which one for which part.” Quick Decision Table Material Strength Best-suited part Watch out ABS Rigid, dimensionally stable, good surface, economical Box/enclosure, panel, cover, general structural Weak in UV/outdoor PP Flexible, fatigue- and chemical-resistant, hinge Lidded boxes, living hinge, containers, automotive Less rigid, hard to bond/paint PE Chemical resistance, low friction, tough Sealed containers, bumpers, low-load parts Low rigidity, hard to bond POM High rigidity, low friction, precise dimensions Gears, bearings, clips, sliding mechanisms Expensive, hard to bond, heat-sensitive PA (nylon) Tough, wear- and temperature-resistant Gears, load-bearing parts, wearing components Absorbs moisture (dimensions shift); abrasive if filled Selection by Function Box, enclosure, cover → ABS (or PC) Requires rigidity, dimensional stability and a good surface. ABS is economical and ideal; if impact/temperature is critical, PC (polycarbonate) or ABS+PC. (See Electronic Box/Enclosure Mold.) ...

Plastic prototyping with an aluminum mold is a method for obtaining parts from real injection plastic at a much lower cost and in a shorter time than a steel production mold. The short answer: if your quantity is below ~10,000, your material is non-abrasive (PP, ABS, PE, POM) and speed matters — an aluminum mold + desktop injection molding is almost always the right choice. In this article, we explain the decision with numbers. ...

Fast PCB prototyping is the flow that moves an electronic idea from schematic design to a tested, working board in the shortest possible time. The short answer: with a DFM-clean file and in-stock components, a working prototype can — according to industry data — be produced in as little as 24–72 hours; at MARG the typical end-to-end time is 2–4 weeks. In this article we explain what determines the lead time and what blows up the cost. ...

PCB design is one of the most critical stages of electronic product development. A small mistake can lead to major costs and lost time in production. Here are the most common mistakes and their solutions: 1. Insufficient Copper Clearance If the distance between traces falls below the manufacturing capability, the risk of a short circuit increases. Solution: Enter your manufacturer’s minimum clearance values (usually 0.15mm+) as a design rule. For high-voltage traces, refer to the IPC-2221 standards. ...
