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

From Raw LSR to Finished Part - Every Stage, Visible
Watch TYM's silicone insert mask molding line in operation: precision LSR dosing, closed-mold injection, full vulcanization, and clean automated demolding - all within a single continuous cycle.
Parts exit flash-free and dimensionally consistent, delivering the soft, reliable seal and tight tolerances required for medical and skin-contact applications.
This is what a purpose-built LSR production line looks like when mold, machine, and automation are engineered together.
WHREE IT RUNS
Typical applications
The vertical layout suits parts where silicone is molded onto an insert, or where two-station loading speeds production.

QUESTIONS
Frequently asked questions
What products is the TYM-R Series suitable for?
The TYM-R is purpose-built for LSR overmolding applications, including protective masks, automotive overmolded parts, medical overmolded components, and LSR shower heads - any part requiring insert loading, two-material bonding, or complex part-removal routines.
What's the advantage of the turntable (rotary table) structure?
The dual-lower-mold rotary design allows one station to inject while the operator simultaneously loads inserts and removes parts at the other. This eliminates machine idle time caused by manual operations, maximizes throughput, and requires only a single operator.
Why is the opening stroke listed as 400–900 mm (customizable)?
Overmolded parts often require significant mold-open clearance for insert loading or robotic part removal. The adjustable stroke accommodates mold stacks of varying heights and supports seamless robotic arm integration for fully automated production.
What is the benefit of the three-column guide design?
The three-column layout opens up the operator-side access area compared to conventional four-column designs, reducing interference with insert fixtures during loading and part removal. It also improves platen parallelism and clamping rigidity, extending mold service life.
Do you also supply molds for this machine?
Yes. TYM operates a dedicated mold division (tymmold.com) offering LSR injection mold design and manufacturing optimized for TYM-R machines. We also accept customer-supplied molds and provide process validation and trial molding services.
How do I request a quote or arrange a trial run?
Submit your inquiry via gdtym.com or tymsilicone.com. Provide part drawings, estimated annual volume, cavity count, and target LSR material - our engineers will respond with a machine recommendation and quotation within one business day.
