From RFQ to Start Up: How a TK Mold Program Runs
Most of the risk in an offshore mold is in the handoffs: between your engineers and the toolmaker, between design and the steel, and between the trial in China and the start up in your plant. TK runs the program in one sequence with one project manager, and TK’s project managers average 15 years with the company.
Built to Demanding North American and European Standards
TK machines molding inserts to 0.002 mm in temperature and humidity controlled workshops, so parts are held to the machining data and inserts go together without hand matching or flying the mold. That is what makes cavities interchangeable on a 128 cavity mold and what keeps a spare insert a drop in replacement years later.

Steel, Components and Hot Runners
- Tool steel from ASSAB, GMH Gruppe and Schmolz+Bickenbach, checked on arrival by spectral analysis and hardness testing.
- Standard components from HASCO, DME and Meusburger, the same catalog parts North American mold shops already stock.
- Hot runners from Synventive, HRS, Incoe and Milacron, matched to the resin and the gate.
- Mold base and plate work on machines with up to 3.2 m by 3.0 m by 0.8 m of travel in TK’s automotive tool shop.
See the custom injection mold tooling page for steels, mold classes and build options.
Conformal Cooling with 3D Metal Printing, and RHCM
Straight drilled water lines cannot follow a deep core or a curved wall, so the steel runs hot where the line cannot reach and the cycle waits for it. TK prints cooling inserts in house with channels that follow the part, and uses rapid heat cycle molding where the surface has to come out of the mold finished.
Conformal Cooling at TK
- In house printing on a 3D Systems DMP 350 in maraging steel 1.2709, 33 to 37 HRC as built and 50 to 56 HRC age hardened, polished to SPI A2.
- Up to 35% shorter cycles, with less warpage from even cooling.
- Documented: a 12+12 two shot flip top cap mold went from 21 s to 17 s.
- Print size up to 275 by 275 by 420 mm per insert, and diffusion welded inserts as a second route.
More on the conformal cooling page, with a savings calculator.
2K and 3K Multi Shot, LSR, Insert Molding and IMSE
Molding two materials in one mold removes a bonding or assembly step and puts the soft grip, seal or second color exactly where the design wants it. TK builds the molds and runs them: 60 of TK’s molding presses are 2K, 3 are 3K and 32 run liquid silicone rubber.
- 2K and 3K: hard and soft bonding for grips and seals, and two color parts, with multi shot molds run on TK’s own 2K presses. More on the multi shot page.
- LSR overmolding onto engineering plastic, metal or glass.
- Insert molding of metal, glass, ceramic and circuit board inserts, sealed to IP68 with air leakage control up to 7 bar.
- Injection compression to lower internal stress and even out wall thickness.
- IML and IMD for dead front panels, graphics, waterproof windows and conductive circuits.
In Mold Structural Electronics (IMSE)
With IMSE, developed with TactoTek, circuits and components are printed and mounted on a film, the film is formed, and plastic is molded around it. TK’s IMSE example compares a conventional electronics assembly with the molded part:
Molding, Secondary Processes and Production Bases
TK does not hand the mold off and walk away. The same group molds, decorates and assembles parts on 503 presses, most of them high speed and electric machines from Europe and Japan, and runs 7,000 tons of resin a year through them. For large automotive molds TK tries out on presses up to 2,800 T.
Molding presses by clamp force, 503 in total. By type: 343 horizontal, 40 vertical, 60 two shot, 3 three shot, 32 LSR and 25 high speed.
| Base | Work | People | Floor space |

| Huizhou, China | Molding, LSR molding, spray painting | 550 | 38,000 m² |
| Suzhou, China | Mold making, molding, secondary processes | 400 | 23,000 m² |

Interactive Mold Program Planner
Enter your annual volume, the cycle time you expect and how many hours the mold will run. The planner works out how many cavities you need, picks a practical cavity layout, shows the spare capacity it leaves, and points you to the TK capabilities that fit your part. Open “Show the math” to check every step.
Show the math
A first estimate for planning. The cavity layouts are common practice, not a TK quote. Cycle time, the right cavitation and the mold type are set in DFM with Moldflow, and depend on part size, wall thickness, resin and the press. Default numbers are an example only.
