Plastic Injection Molding Services

AIM Processing runs custom plastic injection molding programs for design engineers, purchasing teams, and business owners who need parts that show up on time, built right the first time — backed by engineers involved before a tool is ever cut.


When your current molder promises four-week lead times that instead stretch into ten, that delay impacts your customers, your business and your bottom line. AIM Processing runs custom plastic injection molding programs built to prevent that, across a wide range of part sizes, volumes, and industries, backed by engineers who get involved before a tool is ever cut.

We work with design engineers, purchasing and supply chain managers, and business owners who need one thing in common: a molder who shows up with the part they were promised, on the day they were promised it and that meets or exceeds quality expectations. Our job is to make your job easier. Now we’ll tell you how we do it.

 

Custom Plastic Injection Molding Solutions

We begin the business relationship with a conversation about your part, not with a quote form.

  • Product development support.
    Our engineers review your design for manufacturability before tooling starts. As part of this process, we run a mold-flow analysis to simulate filling and cooling. This allows us to identify issues on a computer screen before the job hits the shop floor. We can point to several instances where this helped resolve persistent issues for our customers. In one case, when a previous molder couldn't resolve a persistent sink mark issue for a medical device manufacturer, our engineers identified a foam additive that solved it.

  • Material selection guidance.
    We can work to spec, but for customers that need more guidance, we can help select resin from among 700-plus active materials. Resin selection depends on required mechanical strength, chemical resistance, dimensional stability, ESD requirements, and biocompatibility.

  • Low- to high-volume production.
    Whether you need a few thousand units for a new product launch or a running program in the millions, we scale to your build plan.
  • Tool transfers and production launches.
    Moving a program to a new molder can be a risky venture. At AIM, a degreed engineer owns your transfer project from day one, running daily 5-minute status updates during the active period. We've completed transfers of 16 to 20 tools over several months without a single back-order event.

Why Choose AIM Processing?

 A wide range of sizes and capabilities

AIM Processing runs parts across a broad size and complexity range, from precision micro components to larger, more complex geometries. If your program needs different part sizes across a single product line, you can find all the assistance you need under one roof. 

 An engineering-driven approach

Our engineers work alongside your team at the design stage, running mold-flow analysis and material selection guidance before the tool is built. That's the difference between catching a manufacturability issue on screen and catching it on the production floor. 

 Manufacturing built for reliability, not just capacity

Our facility runs 24/7, which supports Kanban stocking agreements that keep inventory ready to ship, off your balance sheet, and lets us respond fast when your schedule shifts. Current customers find value in this system, praising our company as a “critical link” in their supply chain.

 ISO-certified quality systems

We've held ISO 9001:2015 certification since 2013, backed by statistical process control and metrology equipment including SmartScope and CMM verification on every program. 

 Reliable delivery and customer support

98%+ on-time delivery. Less than 0.001% return rate. An average customer relationship of 20-plus years. Those numbers exist because of how we run the business, not because of how we describe it. 

Plastic Injection Molding Capabilities

  • Precision molded plastic parts across a wide span of sizes and geometries, including components with features as fine as hair-thin holes, achieving 100% yield at millions of cycles per year.

  • Engineering-grade materials, including specialty resins for medical, electronics, automotive, and industrial applications, selected through a documented material selection process.

  • Tight tolerances, holding as close as ±0.001 in. on precision components without sacrificing repeatability at volume.

  • Secondary operations and assembly, including overmolding, insert molding, pad printing, laser etching, ultrasonic welding, heat staking, and mechanical assembly, so more of your product leaves our facility ready to ship.

Material Selection.
We match resin properties to your application's mechanical, chemical, and regulatory requirements.
Tooling & Validation.
We coordinate with a network of specialized toolmakers, then validate tooling against your specifications before production begins.
Production Manufacturing.
Scientific molding methodology controls the variables that drive part consistency, for every run.
Quality Inspection & Delivery.
Statistical process control and advanced metrology confirm every run meets spec before it ships on your schedule.

Benefits of Plastic Injection Molding

aim-step-04-ejection
Cost-effective production at volumes ranging from low-volume runs to millions of parts per month.
aim-step-02-injection
Consistent quality, evidenced by a return rate under 0.001% across the parts we ship. 

aim-step-05-inspection
Design flexibility to produce complex geometries, tight tolerances, and multi-material assemblies in a single program.
aim-step-01-clamping
Scalable manufacturing that grows with your product, so a supplier fit for your prototype run is still the right fit at full production volume.

Frequently Asked Questions

What is plastic injection molding? 

Plastic injection molding is a manufacturing process where molten plastic resin is injected into a precision-machined mold under pressure, then cooled and ejected as a finished part. It's the standard process for producing high volumes of identical plastic components with tight dimensional consistency.

What materials can be molded? 

AIM Processing works with a wide range of engineering-grade plastics, selected based on your part's mechanical, chemical, thermal, and regulatory requirements. Material selection is part of our design review process, not an afterthought.

What production volumes do you support? 

We support programs from low-volume production runs through high-volume manufacturing, running on 37 presses operating 24/7. Our stocking and Kanban agreements let us align capacity to your delivery schedule rather than forcing your schedule to fit ours.

 

Can you assist with part design? 

Yes. Our engineers review designs for manufacturability before tooling is cut, including mold-flow analysis to catch wall thickness, draft angle, and gate location issues on screen instead of after a mold is built. This is standard on every program, not a paid add-on.
