TMC Series Mold Circuit Inlet and Outlet Options
Compare TMC Series inlet/outlet counts by model, and confirm connection locations and details on the current drawing before installation with the supplier.
The TMC series water mold temperature controller inlet outlet connections vary by model: the TMC-60W provides 2-in/2-out ports, the TMC-90W and TMC-120W provide 4-in/4-out, the TMC-180W and TMC-240W provide 6-in/6-out, and the TMC-360W provides 8-in/8-out. Always confirm the arrangement against the current product drawing before ordering piping or scheduling installation.
How many inlet and outlet connections does each TMC model have?
The verified configurations are straightforward: more heating capacity means more circuits, and more circuits mean more port pairs on the controller manifold. The confirmed lineup is:
| Model | Inlet connections | Outlet connections |
|---|---|---|
| TMC-60W | 2 | 2 |
| TMC-90W | 4 | 4 |
| TMC-180W | 6 | 6 |
The larger units follow the same pattern: the TMC-120W matches the TMC-90W with 4-in/4-out, the TMC-240W matches the TMC-180W with 6-in/6-out, and the TMC-360W tops the range at 8-in/8-out. These figures describe the controller’s port count only — they do not tell you how many mold zones your tool actually needs, which depends on the mold design and circuit layout.
Which TMC model matches my mold circuit count?
Start from your tooling, not from the controller. Count the independent cooling or heating circuits on your mold drawings, then choose a mold temperature controller with at least that many outlet pairs. A two-circuit tool pairs naturally with the TMC-60W, while a six-circuit tool points you toward the TMC-180W or TMC-240W. Leave headroom if you plan to run similar tools on the same controller in the future.
- 2 circuits: TMC-60W (2-in/2-out)
- 4 circuits: TMC-90W or TMC-120W (4-in/4-out)
- 6 circuits: TMC-180W or TMC-240W (6-in/6-out)
- 8 circuits: TMC-360W (8-in/8-out)
The listed inlet and outlet counts do not establish the number of mold zones a unit can serve. Confirm the intended manifold arrangement, circuit requirements, and connection plan with the supplier before selecting a model.
Why should you check the product drawing before installation?
Confirm the current connection drawing for the exact model and configuration before preparing pipework or panels. Check port locations, connection details, and any configuration-specific changes with the supplier to reduce the chance of installation rework.
It also protects your quote comparison. If one supplier’s drawing shows a different port count or arrangement than another’s, you are not comparing like-for-like equipment — and the cheaper quote may simply have fewer usable circuits.
What should plant engineers verify before ordering?
Run through this pre-order checklist with your molding or process engineering team:
- Circuit count: Confirm the number of independent mold circuits and match it to the inlet/outlet configuration, per the table above.
- Port orientation and spacing: Check the current drawing so your piping and platform layout fit the physical manifold.
- Connection details: Note port sizes and thread types from the drawing so couplings and hoses are ordered correctly the first time.
- Future tooling: If upcoming molds need more circuits, size up now — stepping from a TMC-90W to a TMC-120W keeps the same 4-in/4-out arrangement, while larger tools may justify the 6-in/6-out TMC-240W.
- Installation clearances: Confirm floor space and access around the controller for hose routing and maintenance.
Including the drawing, circuit information, and site constraints gives suppliers more context for their quotation. Ask them to identify any assumptions or missing information.
What information should you include in a quote request?
A complete RFQ should state the target model (or the circuit count so the supplier can recommend one), the mold circuit layout, required water quality and treatment, plant supply conditions, and any site constraints such as ceiling height or anchor points. Ask the supplier to confirm the inlet/outlet configuration on the current product drawing as part of the offer. That single confirmation eliminates the most common source of installation-day surprises with a mold temperature controller.
Providing drawings, circuit details, and site constraints can make supplier responses easier to compare. Request written confirmation of the quoted connections and configuration.
Frequently asked questions
Does the port count tell me how many mold zones I can control?
No. The inlet/outlet figures describe the controller’s physical connections, not your mold’s zone requirements. Zone count depends on your mold design and circuit layout. Count the circuits on your mold drawings first, then select a TMC model with at least that many port pairs.
What is the difference between the TMC-90W and TMC-120W?
Both models share a 4-in/4-out connection arrangement, so they serve tools with up to four independent circuits from a piping standpoint. Review the current product drawings for both units to compare their other specifications before choosing between them for your application.
Can I run more mold circuits than the controller has ports?
Port count alone does not determine whether a single unit can serve a mold circuit. Confirm the intended manifold design, simultaneous flow requirements, connection arrangement, and model suitability with the supplier.
Where do I confirm the exact connection arrangement?
Request the current product drawing from your supplier before installation. Because port arrangements can be updated between production runs, the drawing shipped with your quotation should be reconfirmed against the drawing for the unit you actually receive.
