Strategies for Selecting a Plastics Assembly Process

Deciding on the best Assembly Process for your application can be an overwhelming task. There are lots of alternatives from which to pick. This varies from mechanical fasteners and adhesives to friction and heat systems. Each of the different alternatives has their unique advantages. Additionally, every seller in the business that you approach may appear to have the most excellent solution.

To settle on the most appropriate decision, every application must be uniquely considered. Each application has its own specific attributes and prerequisites. Regardless of the fact that you may have had success in the past with, suppose, adhesive bonding, the application you are checking on might be more appropriate for Laser or ultrasonic welding. To start selecting the best possible Assembly Process, it is essential that all the properties and requirements be well defined. These include: material, components, part geometry, and the specifications of the end-user. Continue reading “Strategies for Selecting a Plastics Assembly Process”

How Nano-Composite Materials Improve Manufacturability of Parts

Plastics used in the cars was revolutionized after Toyota, in the late 1990’s and General Motors, in early 2002, made the decision to introduce a nano-particulate filler material in the plastic used in the engine covers and side-steps of rear-wheel-drive minivans.

GMC Safari and Chevrolet Astro offered an optional step, which will use a nanocomposite clay as a filler material in the main material- a thermoplastic olefin plastic resin. The plastic is reinforced with the filler material before molding the parts. Southern Clay Inc. in Gonzales, Texas supplies the nanocomposite, which is a clay powder with special characteristics that increase the stiffness and impact resistance of the parts and yet, reduce weight over other materials.

How to Color Your World with Laser Plastic Welding

What does color have to do with laser plastic welding? Everything. Especially if your consumer brand of audio earbuds is recognized globally by its distinctive shade of white, or if your customers expect classy, glossy black appointments on their luxury automobiles. The fact is, there are a lot of very cool things you can do with colors and other additives in the laser plastic welding process, especially in the automotive and consumer product industry – but many designers and engineers aren’t aware of these capabilities. We’ll enlighten you now about the plethora of possibilities and how we can help you add color to your product designs.

UV Laser Depaneling: Taking the Hazards Out of HAZ

How will the heat generated by a laser beam affect my board and components during depaneling? Will it melt edge components into an ugly heap? Or demolish thin flex materials into an unrecognizable blob? We get these worst case scenario questions all the time from PCB designers and manufacturers who have relied on mechanical routers, manual cutters, and other traditional depaneling machines throughout their careers. So it is no wonder that there’s an ongoing concern about a laser’s heat affective zone (HAZ), and the thermal effect on edge components in particular.

The Good Gets Even Better: Flex PCB Laser Etching

Flexibility is a good thing if you’re an Olympic gymnast or Cirque du Soleil performer – and it’s essential for PCB designers and manufacturers whose prototypes and end products demand precision etching on flex PCB materials. For the past 40 years, standard mechanical PCB milling systems have been the tools of choice for straightforward milling operations, and in some cases, they’ve been great performers for flex PCB etching as well. LPKF’s top-performing ProtoMat mechanical PCB milling systems, for example, feature faster spindle speeds, low runout and high resolution for working with substrates as thin as 5 mil for single-sided designs and traces, and spacing as small as 4 mil. All good stuff, so how could it get even better? Laser.
