How Injection Mold Maintenance Keeps Your Injection Mold Producing

Posted by Rena Ivory on Wed,Jul 29, 2015 @ 06:00 AM

Your injection mold is an important asset, so regularly scheduled maintenance is crucial to extending the working life of the mold and the quality of products it manufactures. Regular checkups are important, as they can aid in extending the lifespan of the injection mold. Below are reasons why a company should perform injection mold maintenance on your injection molds.

High repair costs

Whoever said that prevention is better than cure knew exactly what he was talking about. During injection mold maintenance, problems will be identified and fixed immediately and impending issues can also be identified and addressed.

Cost of doing repairs are higher than regular scheduled maintenance because once a mold completely breaks down these repairs tend to be more costly, due to the increased damage to the tool and unscheduled production downtime.

Quality of end product

The functioning status of the injection mold is directly proportional to the kind of products produced. In order to get quality results, the injection mold has to be in good condition. Injection mold maintenance is critical to the protection and dependability of the end product’s quality.

Failure to do so will affect quality and start to produce out of spec components. Ignoring the injection mold maintenance will be neglecting your investment which is a high risk to take.

Once injection molds have undergone several cycles qualified manufacturers will perform inspections, maintenance and cleaning. This means scheduling maintenance carefully.

Reasons Why Over Molding is a Beneficial Manufacturing Process

Posted by Rena Ivory on Thu,Jul 16, 2015 @ 10:40 AM

Though often contrasted, style and substance are not mutually exclusive. Consumers want products that look beautiful while still delivering premium results, and in a world of increasing competition, manufacturers must be able to offer them both. Through over molding, companies can enhance their products both aesthetically and functionally at minimal cost or inconvenience.

An Overview of Over Molding

Over molding is the process of molding one material on top of another. Usually employed to make a product more ergonomic or to make stylistic changes, this process is typically used to combine two types of plastic materials.

The manufacturer uses an injection molding machine to insert raw molten material into the mold. Injection molds can be either vertical or horizontal. Manufacturers tend to get better results with vertical machines, as they lower production costs and increase output by taking advantage of gravity.

The Value of a Documented Tool Transfer Procedure for Injection Molding

Posted by Rena Ivory on Mon,Jul 06, 2015 @ 09:33 AM

When it comes to tool transfer for injection molding production relocation - following a well-executed documentation procedure is critical. This is what makes it possible to have uninterrupted production.

Considerations for Transfer of Injection Molds from Vendor to Vendor

Avoid the inherent stress of the tool transfer by making sure you consider every angle that might be affected by the process. Some of these considerations include:

  • Choosing a financially stable company
  • Verifying the company has a documented tool transfer process
  • Verification that no steps of the process are missed
  • All pertinent tool information transfers should be verified

Make sure you discuss details such as project time lines, expectations and frequency of project updates with your injection molder as early as possible in the tool transfer process.

Documented Tool Transfer Procedures

A tool transfer team should be in place from the very beginning of the evaluation process. The strongest teams consist of a representative from each of the most pertinent departments.

Engineering through production departments need to be appraised of the documented details of the tooling project process so they can understand what to expect when the tools arrive at their facility.

Forming effective partnerships is also essential. Items that need to be provided to your injection molder for the evaluation and start of the project are as follows:

  • Drawings
  • Mold specifications
  • Part information
  • Production details
  • Any other value-adding information or auxiliary equipment

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.
