Why use metal over plastic?

8/8/2016

0 Comments

 
Picture
Designing a product? If you're thinking about manufacturing with metal instead of plastic, think about these 5 great reasons why metal might be a better choice for you:
  • You need strength. Metal is a stronger material than plastic.
  • You need accuracy. Metal can stand up to warping more than plastic. For example, metal sheave gauges last much longer than plastic ones.
  • You need heat and UV resistance. Will your product need to withstand high temperatures without melting or warping? Metal may be your best option.
  • You need your product to look more expensive. Metal simply looks more pricey than plastic. Customers perceive it as better quality and durability.
  • You need good conductivity. Metal is a natural conductor. 

If these factors matter for your production, consider metal over plastic.

Pros and cons of types of metal manufacturing

5/12/2016

Picture
Need to make metal parts but having trouble navigating the processes? Use this beginner's guide to metal parts manufacturing.

SIMPLE: Using Metal Coils or Strips

Stamping: Forming metal coils or strips into shapes (blanks, embosses, and bends, for example) using a press (a single operation or a series of stages)
Metals used:
  • Aluminum
  • Electrolytic steel
  • Stainless steel
For large runs (10,000+ parts)
Pros: Rapid production time (seconds) and most cost-effective part pricing
Cons: Tooling generally costs from $10,000 to $50,000, and tooling changes are limited.

Laser Cutting: Cutting and etching metal using a laser, usually through optics and CNC (Computer Numerical Control) for material or laser beam control. The process leaves a high-quality surface finish and permanently etched parts.
Metals used:
  • Aluminum
  • Sheet steel
  • Stainless steel
For small runs (less than 10,000 parts)
Pros: No tooling needed
Cons: Slower process with longer turnaround time and higher prices

COMPLEX: Using Bar Stock or Melted Metal
Die Casting: Putting liquid metal into a mold under high pressure, commonly used for the production of complex geometries.
Metals used:
  • Aluminum
  • Copper
  • Lead
  • Magnesium
  • Tin
  • Zinc
For large runs (10,000 parts)
Pros: Rapid production time (seconds) and cost-effective part pricing
Cons: Tooling generally costs from $10,000 to $50,000, and tooling changes are limited.

Machining: Drilling and threading bar stock, commonly used in production of nuts.
Metals used:
  • Aluminum
  • Brass
  • Stainless steel
For large runs (10,000+ parts)
Pros: Little or no tooling needed
Cons: Slower process with longer turnaround time and higher prices

3D printing won't compete with mass production anytime soon

3D printing won't replace traditional manufacturing anytime soon says reporter Drew Turney in his TechRadar article "How 3D printing to order is changing manufacturing."

"If you can mass produce a spoon out of metal stamping, 3D printing isn't going to compete with that for a number of years," he says. What 3D printing can compete with: customized parts in low volume such as out-of-circulation spare parts.

"The costs of more accurate machines will be prohibitive to entry into the consumer market for the foreseeable future," adds Turney. "
Of course, in many ways only one thing will drive change, and that's the price of goods.... Along with... ease of use, low financial and technological barriers to entry are giving small 3D printing operators a whole new world to discover."

Massachusetts continues to be a hub for manufacturing innovation - this time in textiles

4/5/2016

A t-shirt that monitors your health, protective gear for firefighters that can withstand the hottest flames, military uniforms that can detect chemical threats, and even clothing that regulates your temperature — cooling you down in the summer or warming you up in the winter. Those innovations are exactly what the new national center Revolutionary Fibers and Textiles Manufacturing Innovation Institute out of MIT might create. Started by the White House and Gov. Baker’s office, the $317 million initiative aims to innovate to benefit American troops on the ground. Also known as Advanced Functional Fabrics of America, the initiative exists thanks to "$75 million in federal funding, $40 million in matching funds from the state, and funds from industry partners" according to the WBUR article "Mass. Chosen To Lead National Textile Manufacturing Innovation Hub."

What politicians hope the institute will create: fabrics and fibers with a range of technical capabilities — from "being incredibly lightweight or flame-resistant to storing energy or having exceptional strength." Applications include advances in health care, military technology, wearable technology, and fashion. Simply put: leaders at the new institute hope to revolutionize textile manufacturing.

The new institute is the eighth manufacturing hub selected by the Obama administration for President Obama’s federal manufacturing initiative called the National Network for Manufacturing Innovation. "Massachusetts already has connections with two regional manufacturing centers — one for photonics and one for flexible hybrid electronics — but this is the first to be based in the state," says WBUR reporter Zeninjor Enwemeka.
​
Nearly 90 businesses, universities, and nonprofits from across the country will comprise the initiative, including:
  • The University of Massachusetts, providing expertise in flexible electronics and wearable technology
  • Quinsigamond Community College in Worcester, providing training for skilled workers
  • Such companies as New Balance, Nike, Bose, and Intel.

"The institute will have a prototyping facility designed to help startups test their first products and scale up new technologies into full production," adds Enwemeka.

What the institute means for Massachusetts manufacturing

The new institute will boost the state’s manufacturing sector and innovation economy, officials say. MIT plans to get the initiative off the ground in six months.

We're improving lead times for you

Picture
To improve lead times for you and cut inventory costs to bring you better prices, we're implementing pull manufacturing. Right now, we're working on a plan to reduce our WIP (work in process) from 14 weeks to one or less. So from the time you email us with your order to the time your order leaves our shipping dock, your parts will flow through our plant in one week or less. We'll do the same with our eight remaining product lines and then implement the entire system. 

The result: shorter lead times and lower prices for you.

How progressive stamping produces hundreds of parts - even in one minute

3/14/2016

0 Comments

 
Picture
If you're looking for one of the fastest methods for producing metal stampings, look to progressive stamping. In progressive stamping, a steel coil moves through a feed in the press and gets stamped by multiple operations in timed sequences as it moves through the press, resulting in final parts.
​
We at Donahue Industries in Massachusetts use progressive stamping to metal stamp thousands of grinding wheel inserts. 

Picture
Progressive dies can produce as few as seven or eight parts per minute or as many as 1,500 parts per minute.... All necessary stations are mounted on a single common die set. These stations are timed and sequenced so that the piece part can be fed ahead a constant given distance called the progression or pitch. Many parts can be tied together allowing many parts to be made with each single press stroke.
