How Colored Resin is Used in the Injection Molding Process

You know enough about mold manufacturing using plastics to know that your customers often need products in colors other than white. However, they also want versatile and durable parts regardless of their color. Colored resin is a popular choice for injection molding because it allows you to fulfill your customers’ requests.

Manufacturers use high-quality colored plastic pellets made from polypropylene or other natural polymers to create colored resin. Depending on the application, fabricators also offer color matching for the colored resin to make injection-molded products. Color matching is especially important in automobile manufacturing, where it is better for dashboards, door handles, and moldings to match a vehicle’s painted surfaces.

The addition of color to the resin before manufacturing products prevents your customers from painting the parts before they market them.

The injection molding process includes injecting the colored resin into the preferred mold and then waiting for it to cool and harden. Important features of components made from colored resin include resistance to heat damage and fading, which means they have long-lasting quality.

Doing Our Part To Help During This Pandemic

As an essential business, Decatur Mold has remained open throughout the ongoing COVID-19 pandemic. We have proudly supported our customers as they have developed solutions to address critical needs that have quickly arisen as a result of this national health crisis. Two recent examples are detailed below.

Fast-tracking an Air Purifier

One of our customers needed to fast track the production of an air purifier system to meet urgent safety requirements created due to the COVID-19 pandemic. Working hand in hand with our customer and leveraging our DFM capabilities to help with our customer’s existing part design, we created a schedule that would allow the seven molds needed to be designed and built in the five week schedule needed to meet their requirements. These molds were built using P-20 steel to run in a production atmosphere along with a required finish of a VDI 27 EDM texture. We completed all the molds as scheduled in five weeks to our customers standards. Sample parts were ran at Decatur Mold and delivered to our customer. These molds have been fine-tuned and are now in production at our customer’s facility! Once again Decatur Mold helped a customer get to the market quickly by leveraging our extensive capabilities, years of experience, and flexible manufacturing options.

Helping our Customer Support First Responders and Medical Staff

Within days of beginning the project above, another customer needed to fast track their project. This customer needed to hit the market with a respirator that would filter the COVID-19 virus to protect first responders and medical staff. Working hand in hand with our customer and again leveraging our DFM capabilities, we helped them develop the part design to insure manufacturability and created a four week schedule required by our customer to build the ten production molds. This program had one very extensively detailed part that created design concerns for our customer. We developed a plan to build a production base with QC-10 aluminum inserts to reduce cost and timing until the part concerns are put to rest and production could start. We would later construct P-20 steel inserts to replace the QC-10 inserts at our customer request. These molds required a VDI EDM texture finish. We completed all ten molds on time to the customer’s standards and sample parts were ran at Decatur Mold and delivered to the customer. Molds are presently in the process of undergoing some minor engineering changes and will be sampled again soon.

Benefits of Injection Molding Services

Injection molding services have risen in popularity within the manufacturing sector. This is in large part due to advances in technology, the widening availability of materials, and improvements within the industry concerning training and quality control. In this post, we will go over a few of the benefits of plastic injection molding.

Plastic injection molding is a process that utilizes heat and pressure to make high-density moldings. This process is highly cost-effective and has made it easier for many manufacturers to increase production without making sacrifices in quality. Key advantages include:

Customization: Molding subjects the plastic medium to high pressures, which allows for a consistent production run. Due to the high pressure on the plastic, it allows for products that exhibit a high amount of detail.

Efficiency: After the mold has been designed and approved, it can be utilized for a high-yield production run. Since only one mold is required for production, this minimizes downtime lost through changing parts or similar processes.

Automation: Adding to the benefits gained from efficiency, plastic injection molding services are highly adaptive to automated processes. Once the CNC machinery has been configured, the processes require minimal intervention from technicians. This reduces labor requirements while keeping operating costs low.

CNC machinery has revolutionized injection molding processes. Contact your local CNC machining contractor to learn more about injection molding options.

The Importance of Accurate Machining for the Appliance Industry

In today’s fast-paced and production-oriented environment, it’s all too easy to consider CNC machining as part of a company’s daily operations. It is important to remember, however, that this school of manufacturing has a purpose–and it isn’t just for breaking quota records or meeting deadlines. Today, we will go over the function of precision, custom machining, and its relation to the appliance manufacturing sector.

Computer numerical machining utilizes computer technology to fabricate parts. Today’s home appliances are more sophisticated than before, which means the components which comprise them require a high degree of both accuracy and consistency. A part that doesn’t fit with the rest of the system means that the appliance won’t work. Worse, it can hold up production.

Custom machining remedies concerns regarding consistency and accuracy. Since these machines are assisted by software, it is easier to fabricate parts with the same specifications as noted in the design documents. Automation facilitates results that are repeatable and have little variance, which in turn reduces the likelihood of a manufacturing defect.

CNC machines are not infallible, however. Since they are utilized for making precision components, they also require maintenance conducted by highly trained and qualified technicians. It is up to the technician to change out tooling, verify fabrication orders, and make any necessary corrections.

When considering custom machining, it is important to team up with a crew you can trust. Contact your local manufacturing company to learn about their CNC machining capabilities.
