Tips to avoid resonance problems in stepper motors
If you need a low-cost motor with simple operation, stepper motors are a solid choice -- they can be driven, step by step, without an encoder or Hall sensor for rotor position feedback. However, according to the motor experts at Portescap, the straightforward design that makes stepper motors so popular can also lead to resonance problems in certain conditions.

Injection Molding: Top tips for designing multipart assemblies
There are many different ways to approach product designs that involve multiple components. To keep things cost effective and efficient, simplify your design, don't make what you can buy off the shelf, explore all of your manufacturing options, and understand the rules of each part of the process. However, it's not always that easy. Here's what else you can do. Great info from Protolabs.

Structural adhesive offers 4x temp stability
Developed primarily for use in the automotive industry and mechanical engineering, DELO has launched an adhesive with exceptionally high temperature stability. DELO MONOPOX HT2999 achieves compression shear strength of 20 MPa at 180 C. This is four times greater than its predecessor and other products on the market. High-temperature-resistant adhesives are in demand for use with electric motors and power electronics. Many products that are currently on the market show a clear drop in performance at temperatures above 150 C. DELO's new structural adhesive can handle it.

Xometry: What does it mean to be the 'Uber of Manufacturing'?
Xometry consolidates the supply chain by having a single storefront for multiple manufacturing options. When you place an order for CNC machining, injection molding, compression molding, 3D printing, sheet metal fabrication, laser and waterjet cutting, or urethane casting, it is sent through Xometry's extensive Manufacturing Partner Network. This is a vetted network of professional manufacturers from job shops to serialized production facilities. Xometry uses its AI-driven technology to pair projects with those manufacturers best suited to produce your parts on time and to your requirements.

Image - Lower friction than comparable sliding bearings
Lower friction than comparable sliding bearings
AutomationDirect has added WON linear bearings and rails to its line of mechanical power transmission products. WON linear bearings generate lower friction than comparable sliding bearings. With less friction to overcome, less power is required to move a load, higher speeds can be achieved, and greater efficiency is reached. Available in various sizes to meet the needs of any specialized motion project.

Image - Higher-torque rotary tables for bigger applications
Higher-torque rotary tables for bigger applications
The new RTMB+ high-precision indexing tables from ETEL are the ideal solution for large-diameter manufacturing applications where high repeatability and short indexing times are required, such as in the back-end semiconductor, electronics, automation, or printing industries. A unique encoder-bearing solution provides the RTMB+ with the best torque-to-volume ratio on the market, and with the integration of a new water-cooling feature, users can expect an up to a 30% indexing gain compared to an equivalent air-cooled version. New diameters and heights available.
