Advantages of Utilizing Robotics in Plastic Injection Molding

Posted by Rena Ivory on Thu,May 21, 2015 @ 01:56 PM

Robotics in plastic processing is the natural progression of technology. It has ushered in a plethora of possibilities that have improved and supported the industry dramatically. 

Motivation for implementing robotics and downstream automation has primarily been to increase productivity, reduce cycle times, increase part quality and facilitate the assembly of small harder-to-handle components. 

Most robots are designed to be helping hands and/or high-tech tools. Using robotics to complete as many tasks as possible generates more time and resources for other required hands-on processes.

Robots are programmed to carry out specific repetitive actions without variation. It is done with extremely high degrees of accuracy. These actions are determined by programmed routines that specify the direction, acceleration, velocity, deceleration and distances. 

Industrial robots often use precise guidance and have the ability to adapt to different part-types using intelligence-based features. These features include; vision, integrated force and sensing capability. Because of this, robotics enables manufacturers to achieve specific levels of flexibility, multitasking and automation of a variety of functions for lower-volume applications.

Why You Must Optimize Cooling and Venting in Plastic Injection Molds

Posted by Rena Ivory on Wed,May 06, 2015 @ 09:25 AM

Two aspects of injection mold design that have great impact on part quality are cooling and venting. If the injection mold has poor cooling, the result could be increased cycle times, scrap and dimensional problems while inadequate heat could result in short shots and poor surface finishes. Venting allows for displaced air in the cavity to escape. If there is inadequate venting, gas burns or non-filled parts can result. If there is too much venting, excessive flash will be the result.

Optimizing Cooling

The biggest problem with the cooling process for plastic injection molding is that a poorly cooled part increases issues that are difficult to resolve. Some of these issues include an increase in cycle times, an increase in scrap, as well as additional problems with part dimensions.

This is why optimization of the cooling processes is so important. Cooling includes a lot of variables such as:

  • The thermal properties of the plastic being molded and the materials used in mold construction
  • Energy balance from melt preparation to cooling cycle time
  • The influence of coolant flow rate on heat transfer efficiency 
  • Mold temperature controller selection
  • Quality design practices for optimum mold cooling

Every plastic part produced requires very specific amount of energy to plasticate solid resin pellets.  This means that an identical amount of heat energy needs to be removed before it will form a stable part. It is important to remember that energy out - needs to equal energy in.

Scientific Injection Molding Facilitates Quality Plastic Components

Posted by Rena Ivory on Wed,Apr 22, 2015 @ 04:07 PM

To best accomplish consistency for the highest quality plastic injection molding components - sound principles need to be applied across the field. Scientific injection molding principles are the only approach to repeatable quality product.

Repeatability is key for injection molding. The nature of this process provides the ability to produce the exact same device over and over with exactitude. Repeatability is essential for considering medical devices - as sterility and precision, process validation and control are of utmost importance to create true reliability. 

There are several factors that effect repeatability: 

  • Fill time for the flowable material into the mold 
  • Screw design 
  • Consistent melt quality 

Critical advantages are achieved anytime these common principles are applied to the process. It is the only way to consistently accomplish controlled production end products.

Purpose of Project Management for Injection Mold Building

Posted by Rena Ivory on Thu,Apr 09, 2015 @ 10:53 AM

Project management for injection mold building is essential. The project management office (PMO) is comprised of a group of professionals who focus on defining the scope and maintaining the standards set for any injection mold building project to be accomplished by the company.

The goal of an effective PMO is to achieve all benefits from the standardized project management processes, methods and policies. The PMO administrators are tasked with sourcing all required documentation, metrics and guidance for the execution of all project requirements.

The PMO follows every project related task from start to finish. This office provides a strategic tool for keeping decisions and implementations moving in a consistent manner toward every project goal. This is accomplished by detailed reporting on all problems, activities and requirements involved.

Injection Molding Still a Steadfast Manufacturing Process

Posted by Rena Ivory on Wed,Feb 25, 2015 @ 09:57 AM

The custom injection molding process is now more than 150 years old. It remains one of the most dependable manufacturing processes still in use today. The plastics we know of today owe their origins to the late 19th century European and American chemists who experimented with many kinds of rubber and residue from various chemical mixtures.

Reasons Why Mold Fill Simulation Enhances Your Plastic Product Design

Posted by Rena Ivory on Wed,Feb 11, 2015 @ 10:36 AM

Mold filling simulation helps mold builders stay competitive. It does this by enhancing efficiencies and helping to better meet customer expectations - while also creating more business opportunities. Mold fill 3D simulation is a very helpful tool for injection molders and plastic part designers because it uses software to simulate the filling, packing and cooling of a molded plastic part virtually.

Color Consistency in Plastic Injection Molding

Posted by Rena Ivory on Wed,Jan 28, 2015 @ 10:28 AM

Color consistency for injection molded parts poses a challenge.  This becomes apparent when it comes to mating parts in any assembly where colors need to match 100 percent.  

Pre-colored plastic is used in the injection molding process so the molded part emerges in the specified color and finish.  There is no need for painting, plating or other finishing steps. The color becomes an integral part of the component, and the color is not just on the surface. The advantages to this approach include:

  • High quality, long lasting – no paint scratch, peeling issues
  • Coloring withstands harsh environments
  • Eliminates secondary operations for lower costs
  • Environmentally friendly process eliminates or reduces environmental impact 
  • FDA compliant molded-in coloring available
  • Flame-retardant grades available

Achieving Custom Colors

  • Choose a predefined color - usually Pantone
  • Assure raw material availability - as not all Pantone colors have material available
