For companies that require tight-tolerance, critical-use plastic injection molding capabilities, it's important to partner with a supplier that can consistently deliver quality products and value-added services to support these solutions. When evaluating your list of potential full-service injection molders, however, you may ask yourself, "Do I want a partner that is specialized or diversified?"
From a supplier and customer viewpoint, there can be risks involved in choosing a specialized molder, and the guideline below explains why.
Total delivered cost (TDC) is the amount of money it takes for a company to manufacture and deliver a product. The definition sounds simple enough, yet all that TDC entails — sourcing raw materials, manufacturing bulk and intermediate products, finished goods packaging, inventory holding, transportation, distribution, and final delivery — reveals its complexity and considerable impact on the bottom line.
What does 2019 hold for the plastics industry? Several trends that emerged in 2018 continue to be refined and amplified heading into the new year:
With careful planning, complex injection molding can reduce costs, optimize functionality and improve aesthetics in medical devices.
The practice and purpose of qualifying a tool is at the very core of scientific molding. This critical step ensures consistent and repeatable production of flawless molded parts by having engineers push the tool relentlessly under realistic conditions (and sometimes beyond). Their goal is to identify and correct weaknesses before the tool is called into action.
Here’s a look at the basic step-by-step process of scientifically qualifying a tool:
The Kaysun Blog is a valuable year-round resource for advice and information about complex injection molding. We have our subscribers to thank for its continued popularity, and look forward to providing you with even more helpful insights throughout 2019.
For now, let’s take a look back at the four most popular blog posts of 2018:
In the manufacturing world, “lean” principles reduce inventory and work in process, improve quality, boost productivity, and ultimately lower costs. Lean originated in Japan decades ago and has been readily embraced in manufacturing sectors around the world, especially the automotive industry.
With increasing global competitiveness, lean principles have never been more important for making U.S. companies competitive. One of the most simple yet effective lean tools is value stream mapping, which can be implemented within days and can reap impressive results in a short period of time.
There is little room for error when designing plastic parts for critical-use applications. Anything that could stand in the way of uncompromised performance or end-user safety is unacceptable; there’s too much at risk given the potential for significant issues surrounding recalls, warranty claims, property damage and personal injury. And, no company can afford to lose customer trust.
When engineering-grade resins were introduced in the 1950s, some auto manufacturers were unfamiliar with the benefits of metal-to-plastic conversion, i.e. how to design plastics into products, and how to manufacture with plastics. Today this practice, also known as “lightweighting,” is becoming increasingly popular with automakers as they race to comply with a federal mandate calling for automobiles to average 54.5 miles per gallon by 2025.
