When choosing injection molding, it’s crucial to consider your entire project from beginning to end. This means thinking about the types of value-added services from which your project can benefit. Choosing a manufacturer with the value-added services your project needs can provide a one-stop-shop for your manufacturing needs, saving time and money.

This blog will guide you through the benefits of value-added services and several types of services that are common solutions for plastic injection molding projects.

Benefits of In-House Value Added Services

An injection molding manufacturer with a range of in-house value-added services is your one-stop-shop for plastic injection molding. Partnering with a manufacturer that can provide for all of your production needs in one location delivers the following advantages:

  • Cost Saving. In-house value-added services can reduce miscellaneous costs on secondary processes and save on labor costs.
  • Time-Saving. A single location for production can result in improved efficiency and time management.
  • Quality Assurance. In-house services ensure that product testing is consistent from start to finish.

Welding/Machining

Plastic injection molded parts often need secondary services to create a finished product or before moving on to assembly. Welding and machining are common secondary services for plastic injection molded parts.

One common value-added welding service is ultrasonic plastic welding. This beneficial service can join two thermoplastic pieces using heat energy from high-frequency mechanical motion. High-frequency electrical energy is converted into high-frequency mechanical motion, which is then combined with applied force to create frictional heat along the mating surfaces of the plastic components. The heat forms a molecular bond as it cools.

Other value-added machining services that are commonly used with plastic injection molding include:

  • Heat staking
  • Milling
  • Tapping
  • Reaming
  • Drilling

Assembly

Assembly is a complicated and essential step for completing many injection molded products. In-house assembly services provide a high-value product with improved efficiency and cost-effectiveness.

Complete assembly services can reduce the cost of materials and ensure assembly is efficient and streamlined. Injection molding manufacturers can also use specialized injection molding techniques and molds to reduce the need for secondary assembly, delivering a seamless product.

What Is Injection Mold Maintenance?

Injection mold maintenance refers to the scheduled cleaning and repairs done to keep an injection mold in optimum working condition. Maintenance can be done routinely over the life of the mold or whenever a problem arises. Regular maintenance helps eliminate the risk of down time due to part failures.  Abtec Inc. provides life of the tool maintenance for tools built and run at Abtec Inc.

What Issues May Arise If Molds Are Not Maintained?

With time, molding processes wear a mold to compromise its quality and performance. Ideally, a fine layer of materials builds up, albeit slowly, on the mold surfaces and, if it is not removed, this deposit dents the tool. This results in a range of defects, including flashes that reduce efficiency.

What Are the Long-Term Benefits of Proper Injection Mold Maintenance?

You don’t have to wait until typical maintenance issues arise before undertaking appropriate maintenance on your injection molds. Undertaking regular preventive maintenance helps lower overall production costs while ensuring optimal performance of your equipment. The following are the long-term benefits of a properly maintained mold:

Better quality and longevity: High-quality equipment and tools are a costly investment. Continual mold maintenance guarantees better quality and longevity while reducing the total cost of ownership.

Prevents inefficiencies: Worn-out parts undeniably affect product quality. An effective way to avoid product imperfections and inefficiencies is to be diligent about performing preventive maintenance.

Cut costs: Failure to carry out mold maintenance results in significant repair or replacement costs. It is a lot cheaper to perform regular maintenance than to repair or replace a broken tool.

Common Defects of Molds from Poor Maintenance

Poor maintenance can result in a range of severe defects that affect the product’s safety, performance, and function. These defects include:

Burn marks

Burn marks on molds appear as black or rust-colored discoloration at the edge of a molded plastic part. Burn marks in injection-molded parts are caused by either trapped air or resin or overheating in the mold cavity during the injection.

Flash

Many manufacturers also refer to flash as “burrs” or “spew”. Flash refers to a condition with excess molding material appearing as a protrusion at the component’s edge. Such defect occurs because some materials flow out of the intended channels. They then enter the space that occurs between the tooling plate. Some may also flow in at the injection pin. Although it is a subtle defect, a flash may be an obvious defect is obvious on products and caused by improper exhaust system.

The process of bringing a new product to market involves many steps, including designing the component and creating prototypes to test out the design. After the design is finalized and the prototypes are evaluated, you may also want to produce a small number of pieces for internal or external product testing purposes before proceeding to full production. In the case of injection-molded components, one option for producing these pieces is short run injection molding—also known as small-volume, low-volume, or small-batch production. This production solution enables you to generate a limited batch that you can use to gauge market reaction so you can appropriately scale production to meet actual consumer demand.

Need help with a short-run injection molding project? The injection molding experts at Abtec are here to help! We can assist you at every step of your project, from design to prototyping to production, ensuring you receive the components you need how and when you need them.

Benefits of Short-Run Injection Molding

Short-run injection molding offers numerous benefits. For example:

  • It serves as a bridge between the prototyping and full production stages. Since short-run injection molding produces only a small number of pieces, it allows the production team to push out a product that can still be adjusted later on depending on its performance in the market.
  • It produces high-quality components. Since short-run injection molding accepts automation technology and utilizes low-cost, high-quality materials, it easily outputs superior parts and products at competitive prices.
  • It allows companies to reduce in-house inventory while meeting lead-time demands. Short-run production quickly produces finished components, so they can be sent back to the customer and introduced to the market in a shorter period. As a result, companies can have parts produced and delivered on an as-needed basis.

At Abtec, Inc., we specialize in custom injection molding, creating tools and parts for customers all over the world from prototype to large production runs. Plastic injection molding is a manufacturing process that involves injecting liquified plastic into a mold, allowing it to conform to the shape of the mold and harden to create a specific shape. This beneficial process has numerous applications in many industries, including the medical industry.

Components and devices for the medical industry must comply with strict industry standards and be made from durable, reliable, and FDA-approved materials. Plastic injection molding not only meets these criteria, but it also offers a host of additional benefits for the medical industry.

The Standards Met & Materials Commonly Used

Parts made for the medical industry must conform to strict standards due to the nature of their use. The FDA outlines different requirements for implantable devices and those being used for medical instruments, and other external use; therefore, it is crucial to consider your application when selecting a medical-grade plastic for the molding process. Other factors such as strength, resistance to heat and chemicals, and operating environment must also be considered when selecting a material to ensure that the part will hold up while in use.

medical grade plasticsCommon medical-grade plastics that can be used with injection molding include:

  • PP. Heat and radiation resistance over extended periods
  • PEEK. Resistant to chemicals and high temperatures, resists fatigue and cracking, works well in radiation-prone environments, and easily sterilized.
  • Polycarbonate. Flexible, high heat resistance, transparent, UV resistance, durable, and resistant to flames.
  • Polysulfone. High temperature with high mechanical strength and rigidity. Good creep strength that is remarkably high over a wide range of temperatures.
  • POM. Resistant to multiple cleaning and disinfection agents, and to a number of solvents. It can be steam sterilized by medical industry’s usual methods, and will maintain good strength, stiffness, and dimensional stability.
  • PEI. Remarkably high creep resistance over a wide temperature and a high permanent operating temperature. Resistance to hydrolysis, along with dimensional stability
  • Polyphenylene Oxide. Strong with outstanding mechanical, thermal and electrical properties. Very low moisture absorption, low thermal expansion, excellent insulating properties, flame resistance, and dimensional stability over a wide range of service temperatures.
  • Polyphenylen Sulfide. A semi crystalline, high temperature thermoplastic polymer. Chemically resistant polymer with amazing mechanical strength, even at temperatures above 200°C (392°F), very stable dimensionally with low susceptibility to creep.

There are many benefits to injection molding for the medical industry, the most prominent being how easily and quickly supplies can be made. Unlike other materials, plastic can be easily injected into a mold to take almost any shape needed, curing into a durable piece of equipment with high levels of precision. This helps to keep prices low, allowing medical facilities to remain sufficiently stocked with important instruments without excessive costs. Cleanliness is also a benefit, as many of these plastics are easy to clean and sterilize without issue.

Abtec Provides Medical Injection Molded Parts

The injection molding process follows these steps:

  1. Create a mold. Injection molding requires a pre-made mold for the material to be injected into. This can be a template for existing pieces or a custom design.
  2. Inject. Pelletized resin which is heated to liquid, is injected into the mold. The plastic fills in the spaces within the mold, forcing out air through tiny vents along the sides.
  3. Cooling. The melted plastic is cooled, allowing it to harden. This is done with a network of water pumps or air vents built throughout the mold that displace the heat from the plastic.
  4. Remove and clean. Once hardened, the part is removed/ejected from the mold and the part is (if necessary) cleaned of any debris or bits of unnecessary plastic.
