BUILT INTO EVERY MODEL
Key features of the TYM-Y LSR injection molding machine
Six characteristics that define how the TYM-Y machine run on the production floor.
Dual independent clamping units
Two independent vertical clamping systems allow sequential or simultaneous molding processes, improving production flexibility and cycle efficiency.
Dual independent injection units
Two dedicated LSR injection systems independently meter, mix, and inject different silicone materials, ensuring precise shot control and excellent bonding quality.
Two upper molds & three lower molds
The unique 2-upper / 3-lower mold configuration enables continuous production by alternating molding cycles while reducing machine idle time.
Two-color & dual-hardness molding
Produce two-color, dual-durometer, or multi-functional LSR components in a single molding process without secondary assembly.
Integrated intelligent control
Both clamping units and injection systems are managed through one centralized control platform for synchronized operation, recipe storage, and simplified parameter adjustment.
High-precision LSR metering system
Independent 1:1 metering, dynamic mixing, and direct-pressure injection guarantee excellent color consistency, material distribution, and repeatable product quality.
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 can the TYM-D Series produce?
The TYM-D Series is designed for manufacturing two-color, dual-hardness, and multi-functional liquid silicone rubber components, including baby products, medical devices, automotive seals, wearable products, and premium consumer goods.
Why use two independent injection units?
Independent injection systems allow different silicone colors, hardness levels, or material formulations to be processed separately, ensuring precise dosing, excellent bonding strength, and consistent product quality.
What is the advantage of the dual-clamping structure?
Two independent clamping units operate alternately, minimizing idle time and improving production efficiency while supporting complex multi-shot molding processes.
Can the machine produce different silicone hardness combinations?
Yes. Each injection system can process silicone materials with different Shore hardness, allowing soft-hard combinations or functional multi-material products to be molded in a single cycle.
Do you provide two-color LSR molds?
Yes. TYM designs and manufactures custom two-color liquid silicone molds, cold runner systems, and complete automation solutions tailored to the TYM-D Series.
Can the machine be integrated with automation?
Absolutely. The TYM-D Series supports robotic loading, automated demolding, vision inspection, and complete turnkey production lines for high-volume manufacturing.
