Metal and Plastic in One Assembly: Somebody Has to Absorb the Error
An industrial actuator assembly arrives as two drawings from two processes. An aluminum alloy flange and support ring. A plastic actuator housing. Each drawing is achievable. Each part can be made comfortably within its own tolerance. And the assembly can still fail to go together — because the question that
Every Unit or None: Why a Lifting Device Cannot Be Sampled
A smart garage hoist is not one part. It is dozens of molded plastic structural components, a transmission, a controller, fasteners and a housing, and every one of them has to be somewhere specific, in a specific order, at a specific torque, before the thing works. None of those parts
The Crack Was at the Pin: What a Failed Boss Tells You About Material Choice
The parts were dimensionally correct. They passed inspection. Two production batches went out the door before the problem surfaced. When it did, it was at the pin mounting points, during assembly, at the customer’s own bench. That detail matters more than the crack itself. A part that fails a dimensional
Bonded or Overmolded? Decide by Failure Mode, Not by Piece Price
A track pin is an aluminum core with a soft rubber buffer around it. On the drawing it is one part. In reality it is two materials pretending to be one, and every decision in the project happens at the line between them. There are two ways to make that
A Custom Plastic Enclosure Is an Assembly Problem, Not a Molding Problem
A US wireless communications manufacturer needed a plastic housing for a switch controller. On the drawing it is a box with walls and tolerances. In the assembly it is something else: the surface a circuit board sits on, the edge that meets a panel, the part an end user touches
