Assembly & secondary operationsMount Vernon, Indiana
Assembly and secondary operations deliver production-ready plastic components
Infinity connects molding to assembly, marking, joining, inspection, and final pack so each added operation supports the same program requirements.
One manufacturing pathInteractive operation planner
A planned secondary-operations path keeps every handoff aligned to the finished component
Choose an operation to explore how the molded part, fixture, process, and acceptance requirements can be considered as one connected program.
Build repeatable assemblies around the component
Program-specific fixtures, work sequence, and component orientation can help turn molded parts into consistent subassemblies or finished assemblies.
- Plan access around critical features and surfaces
- Define the sequence before production launch
- Connect acceptance checks to the completed work
Value-added capability deckJoin / identify / finish
Assembly and secondary operations turn molded parts into production-ready products
Infinity can coordinate the secondary work a program needs without disconnecting it from molding, quality, or delivery expectations.
Bring multiple components into one controlled build
Minor assembly, subassembly, and full assembly can be planned around the part geometry and program requirements.
Integrate an insert into the molded component
Coordinate insert presentation, tooling access, material flow, and finished-part handling as one molding strategy.
Add durable, program-specific identification
Laser marking can support identification and information needs while staying connected to the downstream production flow.
Apply visual information and decoration with control
Pad printing can be integrated for product graphics, indicators, or other defined visual requirements.
Join compatible plastic components into a unified assembly
Ultrasonic welding adds a repeatable joining option when the component design, materials, and performance intent align.
Protect completed work through the final handoff
Final packaging, kitting, and fulfillment can be matched to the product and delivery requirements of the program.
Connected production handoffFive controlled decisions
A controlled production handoff protects each molded component through final release
The right secondary process is only part of the solution. How parts arrive, move, remain protected, and leave each operation matters just as much.
-
01
Mold
Establish the component
Begin with a repeatable molding process and the part requirements that govern every downstream step.
-
02
Present
Control orientation
Move and fixture the part so the next operation reaches the intended feature without avoidable surface risk.
-
03
Add value
Perform the operation
Assemble, mark, print, weld, or pack within a sequence designed around the program.
-
04
Verify
Check the result
Connect inspection decisions to the feature, assembly, or finished condition that matters.
-
05
Release
Protect the handoff
Maintain part identity and protection as finished work moves to packing, fulfillment, or the customer.
Medical + healthcare programsISO Class 8 environment
Cleanroom assembly and inspection support medical components beyond the molding cycle
Infinity's dedicated medical facility supports precision cleanroom molding, assembly, pad printing, and inspection.
Quality at every handoffEvidence stays connected
Inspection and documentation keep assembly decisions connected to the quality plan
Infinity's CMM, electronic vision, inspection, and validation capabilities help teams define what must be checked before, during, and after value-added work.
Explore quality systemsConfirm the input
Part condition, orientation, material identity, and supplied components establish the starting point.
Monitor the critical result
Program-defined checks can evaluate presence, position, appearance, or another agreed requirement.
Release with evidence
Finished assemblies move forward under the applicable inspection and documentation plan.
Technology + talentRepeatable work / skilled decisions
Automation manages repeatable motion while skilled teams protect process judgment
Robotics can present, orient, transfer, and route components. Experienced people remain essential for changeovers, exceptions, problem-solving, and continuous improvement.
AUTOMATED MOTION
Align equipment, fixtures, and work instructions to the program.
Apply judgment when real production conditions require attention.
Use production feedback to strengthen the complete manufacturing path.
