With such a vast range of applications, off-the-shelf plastic components are not always suited for a company’s specific needs. This is where custom plastic manufacturing comes in – the ability to fabricate plastic parts tailored to unique specifications and requirements.

For engineers and product developers, partnering with a custom plastic manufacturer unlocks new levels of design flexibility and functionality. Materials can be chosen based on performance needs, part geometries can be fully customized, and secondary operations like machining, coating, and finishing can be incorporated.

This guide will explore the capabilities of working with a custom plastic manufacturing partner. We’ll focus on services for nylon as well as other commonly used engineering plastics like polycarbonate, polypropylene, ABS, PVC, and polyethylene.

Benefits of Custom Plastic Manufacturing

Choosing custom-designed and manufactured plastic components over off-the-shelf parts brings key advantages:

Flexibility and Customization

With custom plastic molding and fabrication, parts can be tailored to meet exact mechanical, dimensional, and aesthetic requirements. Complex geometries, textures, and features can be incorporated that would not be possible with stock components.

Parts can also be consolidated, reducing the number of separate components needed in an assembly. This simplifies the overall design and improves reliability.

Material Selection

While nylon and other engineering plastics have broad use, they are not suitable for every application. Custom manufacturing opens up more choices like ABS, PVC, polyethylene, and beyond. The optimal plastic can be selected based on temperature resistance, chemical compatibility, electrical properties, and other factors.

Cost-Effectiveness

Although custom tooling is required, plastic injection molding and other processes offer economical per-part costs at production volumes. Creatively designed parts can also replace complex assemblies, reducing long term costs.

For low-volume production runs, custom plastic molding avoids the high initial tooling investment while still benefiting from the efficiency of molding.

Capabilities for Nylon Manufacturing

Known for its strength, wear resistance, and dimensional stability, nylon is one of the most commonly used engineering thermoplastics. From mechanical parts to plastic fasteners, custom manufacturing offers extensive capabilities with this versatile material.

Custom Nylon Molding and Fabrication

All standard plastic molding processes can be applied to produce custom nylon parts:

• Injection molding: Highly repeatable and efficient for complex, high-precision plastic parts in medium to high quantities.
• Extrusion: Creates long plastic profiles with tight dimensional tolerances. Useful for tubes, rods, seals and more.
• Blow molding: Hollow, thin-walled container shapes like bottles and tanks can be blow molded from nylon.
• Thermoforming: Flexible process for producing shallow parts like trays and shrouds from nylon sheet.

Parts can also be machined from nylon stock shapes for prototypes or low volume applications.

Nylon Extrusion, Injection Molding, Machining

For high reliability parts, custom nylon injection molding is recommended over extrusion. Injection molding provides:

• Consistent material properties throughout the part thickness.
• Ability to mold complex geometries not possible with extrusion.
• Excellent mechanical properties in all directions.

When combined with additional CNC machining and finishing, injection molding is ideal for small-scale manufacturing projects that require tight tolerances, precise features, and specified material grades.

Nylon extrusion is best suited for high volume, less complex applications where the plastic profile shape matches the desired part geometry. This is an economical option for long tubes, rods, and basic custom shapes.

Ideal for Durability and Wear Resistance

With its inherent lubricity, toughness, and abrasion resistance, nylon excels in wear-intensive applications like bearings, bushings, rollers, and gear teeth. The material avoids the need for external lubrication.

Nylon’s excellent fatigue endurance also suits it for flexible components and applications involving repeated cyclical stresses.

Common examples include consumable prototype parts for field testing, jigs and fixtures for manufacturing operations, and functional plastic components for harsh service environments.

Custom nylon injection molding combined with secondary machining operations produces durable, complex parts with the wear resistance needed for long service life under demanding conditions.

Capabilities for Other Common Plastics

While nylon covers many general engineering needs, other plastics provide specialized properties. Custom manufacturing gives product designers access to these materials.

Polycarbonate

• Ideal for bottles, drums, tubing, and tanks.
• Colorants and fillers easily added.

With experience across all common plastics, a custom manufacturer can help select the optimal material for an application based on temperature, chemical, electrical, mechanical, and aesthetic requirements.

Secondary Capabilities Expand Possibilities

To produce finished plastic components often requires more than just the initial molding process. Custom plastic manufacturing providers offer a range of secondary services that eliminate the need for working with multiple suppliers:

Prototyping

Ideally, custom plastic parts are designed for optimized manufacturability and performance from the start. A prototyping stage helps achieve this by identifying potential design and tooling improvements early on.

Capable manufacturers offer in-house custom plastic prototyping using 3D printing, CNC machining from plastic stock, and other fast methods. This provides hands-on testing of early concepts before investing in hard tooling.

Machining

Milled, drilled, and tapped holes, slots, threads, and precision features can be added via custom CNC machining. This augments the geometric possibilities of molded parts. Machining also improves dimensional tolerance control.

Plastic welding fuses molded components into larger assemblies and adds molded-in inserts and fasteners. Vibration, spin, and hot plate welding options are available.

Finishing

From basic cleanup to decorative enhancements, plastic parts often benefit from custom finishing operations:

• Media blasting removes mold release agents and improves surface adhesion for printing or bonding.
• Vapor smoothing eliminates fine tooling marks.
• Precision holes can be reamed and honed to exact tolerances.
• Decorative chrome plating or anodizing improves abrasion resistance and aesthetics.

Custom plastic coating via painting, powder coating, wet coating, and plating provides color and improves wear and chemical resistance.

Applications Across Industries

The versatility of custom manufactured plastic parts makes them invaluable across industries. Here are just a few examples:

• Automotive: Engine and interior components, ducting, covers, fasteners.
• Aerospace: Interiors, seats, non-structural aircraft parts.
• Medical: Diagnostic equipment housings, handles, precision instruments, fluid system components.
• Electronics: Connectors, encapsulations, insulators, bobbins, reels.
• Industrial: Material handling equipment, maintenance tools, jigs, fixtures, guards, knobs, and dials.
• Consumer Goods: Appliance parts, sporting goods, furniture, cases, crates, packaging.

Any application that benefits from the reduced weight, resistance to chemicals and corrosion, electrical insulation, and low-cost manufacturability of plastics is a candidate for custom plastic manufacturing.

Partnering with the Ideal Manufacturer

Connecting with the right custom plastic manufacturing partner ensures a smooth project and optimized results. Use this checklist when evaluating capabilities:

• Broad Plastic Material Experience: Look for expertise across nylon, acetal, ABS, polycarbonate, PVC and other engineering resins. Plastics have unique processing nuances – a specialty shop may be too limited.
• Range of Services: Seek secondary operations like CNC machining, finishing, painting, chrome plating, elastomer overmolding, and assembly. This simplifies the supply chain.
• Prototyping: Rapid in-house prototyping shows commitment to engineering development. Testing early prototypes reduces risk and prevents problems.
• Small and Large Production Capabilities: Custom plastic manufacturing providers should be equipped for both short prototyping runs and higher volume production. This avoids sourcing changes down the road.
• Vertically Integrated: Molding and secondary services should ideally be handled under one roof for quality control and efficiency. Shipping parts externally introduces variability and delays.
• Experience with Custom Projects: Evaluate experience working on other unique plastic designs across industries. Look for complex problem solving skills – not just commodity production.
• Engineering Collaboration: Partner with an organization that engages directly with product engineering teams. This ensures manufacturability and optimizes the end design.

Before selecting a custom plastic manufacturing source, request technical reviews of the application and participate in upfront prototyping. This establishes confidence and aligns expectations for the project early on.

However, processing POM is not without challenges. POM is sensitive to heat and moisture, which can affect its quality and durability. It also has a tendency to shrink and warp during cooling, which can cause dimensional inaccuracies and defects. Therefore, choosing the right processing method and avoiding the common pitfalls of POM is crucial for achieving optimal results.

In this article, we will discuss the common processing methods and challenges of POM, and provide some tips and recommendations on how to process POM effectively and efficiently.

Processing Methods

POM can be processed by various methods, depending on the desired shape, size, and function of the final product. Some of the most common processing methods for POM are:

• Injection molding: This is the most widely used method for producing POM parts with complex geometries and tight tolerances. Injection molding involves melting POM pellets and injecting them into a mold cavity under high pressure and temperature. The mold is then cooled and opened to release the part. Injection molding can produce high-quality parts with good surface finish and dimensional accuracy in large volumes and at low cost.
• Extrusion: This is a method for producing POM parts with continuous profiles, such as rods, tubes, sheets, films, etc. Extrusion involves melting POM pellets and forcing them through a die with a specific cross-section under high pressure and temperature. The extruded material is then cooled and cut into desired lengths. Extrusion can produce parts with uniform properties and good mechanical strength at high speed and low cost.
• Machining: This is a method for producing POM parts with precise dimensions and shapes by removing excess material from a raw material using cutting tools such as lathes, mills, drills, etc. Machining can produce parts with complex features and fine details that are difficult or impossible to achieve by other methods. Machining can also be used to modify or improve the surface finish or functionality of parts produced by other methods.
• Other methods: There are also other methods for processing POM, such as thermoforming, blow molding, rotational molding, compression molding, etc. These methods are less common than the ones mentioned above but may have some advantages or applications in specific cases.

Processing Challenges

While POM is a versatile and durable material that can be processed by various methods, it also poses some challenges and difficulties that need to be addressed during processing. Some of the main challenges and difficulties of processing POM are:

• Thermal degradation: POM is prone to thermal degradation when exposed to high temperatures for prolonged periods of time. Thermal degradation can cause discoloration, odor emission, loss of mechanical properties, molecular weight reduction, cross-linking or chain scission of polymer chains, etc. Thermal degradation can occur during processing or storage of POM materials or parts.
• Moisture absorption: POM is sensitive to moisture absorption from the environment or during processing. Moisture absorption can affect the physical properties of POM such as density, crystallinity, melting point, viscosity, etc. Moisture absorption can also cause hydrolysis or oxidation of POM molecules which can lead to degradation or corrosion of POM materials or parts.
• Shrinkage and warpage: POM has a high coefficient of thermal expansion which means it expands when heated and contracts when cooled. This can cause shrinkage and warpage of POM parts during cooling after processing. Shrinkage and warpage can result in dimensional inaccuracies or distortions of POM parts which can affect their fit or function.
• Other challenges: There are also other challenges or difficulties that may arise during processing POM such as mold release issues (POM has a high tendency to stick to metal surfaces), stress cracking (POM may crack under stress due to internal or external forces), gas formation (POM may release gas during processing due to decomposition or reaction with additives), etc.

Solutions and Recommendations

To overcome or minimize the challenges and difficulties of processing POM, some solutions and recommendations are:

• Use proper processing parameters: The processing parameters such as temperature, pressure, speed, time, etc. should be adjusted according to the type and grade of POM, the processing method, the mold design, the part geometry, etc. The processing parameters should be optimized to avoid overheating or underheating of POM, ensure uniform melting and flow of POM, prevent thermal degradation or moisture absorption of POM, etc.
• Use proper mold design: The mold design should be suitable for the processing method and the part geometry. The mold design should ensure adequate venting, cooling, and ejection of POM parts. The mold design should also minimize the stress or deformation of POM parts during cooling or demolding.
• Use proper additives or modifiers: The additives or modifiers such as stabilizers, lubricants, fillers, reinforcements, colorants, etc. should be compatible with POM and the processing method. The additives or modifiers should enhance the properties or performance of POM without compromising its stability or quality. The additives or modifiers should also be used in appropriate amounts and mixed well with POM.
• Use proper post-processing techniques: The post-processing techniques such as annealing, machining, coating, bonding, etc. should be suitable for POM and the part function. The post-processing techniques should improve the surface finish or functionality of POM parts without damaging or weakening them. The post-processing techniques should also be performed under controlled conditions and with proper equipment.

POM is a high-performance engineering thermoplastic that can be processed by various methods to produce parts with excellent properties and versatile applications. However, processing POM also involves some challenges and difficulties that need to be addressed to achieve optimal results. By choosing the right processing method and avoiding the common pitfalls of POM, you can process POM effectively and efficiently.
