Why You Should Outsource Your Injection Mold Project

Custom Injection Mold - Medical EquipmentThe investment to design, implement and maintain in-house injection molding projects can be complicated and costly. Resources needed to devote to this endeavor, such as equipment and personnel, are circumvented by outsourcing such projects to expert companies. Using an outsourced company with a history of experience, and the latest cutting-edge equipment, can easily outweigh the undertaking of in-house operations.

Injection Mold – Lower Costs Because No Capital Investment Needed

Injection molding projects come with requirements that include injection molding equipment, maintenance of that equipment, personnel to design projects, personnel to operate the equipment, and other production employees. Commercial space is necessary to house the equipment and personnel. The capital investment to cover these expenses can be costly. Outsourcing your injection molding projects can be the best solution to keep costs low and have one point-of-contact for all projects.

Using Scientific Injection Molding to Ensure Reliable and Repeatable Product

Plastic Injection MoldingIn a previous article blog, Injection Molding Process Validation Using Scientific Molding, the standard (baseline) process was established. Coupling the established standard (baseline) process, scientific molding principles and monitoring of the four plastic variables during production runs, helps to Ensure Reliable and Repeatable Product.

Injection Molding Process

For this article I am using references to the human body, because like the human body an Injection Molding Process is complex, and also has a lot of variables and interactions that effect the way it runs. To simplify the complexity of both we can externally monitor and observe key variables.

Standard procedure for a doctors visit starts with a check of your vitals (four plastic variables) temperature, heart rate, blood pressure and weight. Observation of how you look and sound, a quick look at your chart (baseline standard process) and a diagnosis is made. This was accomplished with external data of the internal process from common inexpensive instruments when in properly trained and licensed hands can Ensure a Reliable and Repeatable diagnosis.

At Crescent we pride ourselves in having the Scientific Injection Molding Knowledge and Training Certifications that help us to Ensure Reliable and Repeatable Product.

Guidelines for Designing Plastic Injection Molded Components

Injection Molded Plastic componentPlastic injection molding offers many benefits.  In large runs, molding is much cheaper than machining the parts individually, and the manufacturing speed is much faster.  However, when designing a part that will be molded, there are some special considerations that need to be applied.

Because plastic molded parts are injected into mold cavities (voids) and over cores (standing steel), they require draft in order to release from the mold.  Draft is the amount of taper on the vertical walls of the plastic part.  Without draft, a part will either not eject from the mold, or sustain damage during ejection.  Typically, draft angles between 1° and 2° are required, but can vary depending on part restrictions and specifications.

Objectives of IQ, OQ and PQ in Process Validation for Injection Molding

custom injection molding components<h2> Injection Molding Process</h2>

The process of injection molding must consistently create products that adhere to high quality standards. The performance of parts produced must meet customer specifications.

Only through diligently inspecting and validating every aspect of the injection molding process, as well as the final products, can such standards be ensured. To avoid mistakes, substandard products, and inconsistencies, process validation occurs before production gets underway. After a detailed and successful injection molding process is defined, which produces parts that consistently perform according to specific parameters, production can commence.

IQ, OQ and PQ play critical roles in the injection molding process validation procedure.
