BUILT INTO EVERY MODEL
Key features of the 3RT LSR injection molding machine
Six characteristics that define how the TYM-3RT machines run on the production floor.
Customizable Ejection
Multiple sets of ejection mechanisms can be customized, paired with fixed heating moldbases, to reduce mold opening costs.
Lower Tooling Costs
Molds for simultaneous production of two different parts using the same LSR material.
Flexible Knockout System
Suitable for converting solid compression molding processes (such as two-plate molds,multi-layer molds, etc.) to liquid silicone injection molding processes.
DOSING & INJECTION
How the LSR molding system works
Two-component liquid silicone moves from drum to cured part in one continuous, metered path.
Feeding
Components A and B are supplied from the feed drums into the system.
1
>>
1:1 metering
A volumetric metering cylinder doses A and B at a fixed 1:1 ratio.
2
>>
Color dosing
A color pump injects pigment into the stream at the set rate.
3
>>
mixing
The mixing system blends A, B, and color into a uniform compound.
4
>>
Injection
The direct-pressure barrel injects the mixed silicone into the mold.
5
>>
Heat curing
The heated LSR mold cures the part to its final shape

QUESTIONS
Frequently asked questions
What products is the 3RT typically used for?
Common applications include LSR overmolded spatulas, cable accessories, squeegee mop blades, automotive seals and gaskets, and silicone sealing components for wiring harnesses.
How does the fixed heated mold base lower tooling cost?
Because the heating system is integrated into the machine rather than into each mold, individual molds no longer need their own heating circuits - reducing per-mold tooling investment and shortening mold development lead time.
Do you supply molds as well as machines?
Yes. As a manufacturer of LSR machines, precision molds, and turnkey automation lines, TYM can supply matching molds and integrate the 3RT into a complete production system.
What does "converting solid compression molding to LSR injection" mean on the 3RT?
The 3RT lets manufacturers who currently run solid silicone (HCR) compression molds - including two-plate and multi-layer molds - transition to liquid silicone injection on a single platform, reusing similar mold concepts while moving to a faster, more automated process.
What is the difference between the two models?
The L6068-3RT has a 600×680mm tie-bar space and 400–700mm opening stroke; the L7078-3RT has a 700×780mm tie-bar space and 600–900mm opening stroke for larger or taller molds.
