Key features of the TYM LSR injection molding machine
Six characteristics that define how the TYM machine run on the production floor.
Integrated whole-machine control
A single centralized platform manages clamping, injection, metering and color dosing for synchronized operation, recipe storage and simplified parameter adjustment.
German NOVO electronic ruler
High-resolution NOVO position sensing delivers accurate, repeatable position control for stable mold opening, closing and ejection.
Proprietary control software
TYM's in-house developed control system gives full ownership of the operating logic, supporting tailored process settings and long-term maintainability.
CNC precision colorant dosing pump
A digitally controlled color pump meters pigment into the stream at a set rate, ensuring consistent color and uniform material distribution batch after batch.
AB direct-pressure metering cylinder
A volumetric AB metering cylinder doses components A and B at a fixed 1:1 ratio with direct-pressure injection for accurate shot control and reliable bonding quality.
German imported high-pressure hydraulic pump
A high-pressure hydraulic pump provides stable clamping and injection force for fast cycles, smooth mold action and consistent part quality.
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.

See the TYM-W Horizontal LSR Line Mold an 8-Cavity Baby Pacifier - Every Stage,
Watch TYM's 8-cavity baby pacifier molding line in operation on a horizontal LSR machine: precision LSR dosing, direct-pressure closed-mold injection, full vulcanization, and clean automated demolding - all within a single continuous cycle.
Pacifiers exit flash-free and dimensionally consistent, meeting the tight tolerances and material safety required for infant feeding and food-contact applications.
This is what a purpose-built LSR production line looks like when mold, machine, and automation are engineered together.
.
Typical applications
The horizontal layout suits parts that demold automatically, and large tie-bar windows (450/550×1100 mm) support wide or multi-cavity molds.

Frequently asked questions
What products can the TYM-W Series produce?
The TYM-W Series is designed for liquid silicone rubber components such as automotive wiring-harness seals, baby pacifiers and nipples, menstrual cups, medical valves and stoppers, and general food-contact or industrial silicone parts.
What is the advantage of the horizontal direct-pressure structure?
The direct-pressure horizontal layout enables fast mold adjustment and precise position control, making it well suited to fully automated demolding and continuous high-volume production.
What does the model number mean?
The number encodes the tie-bar window. For example, TYM-W4040 = 400×400 mm and TYM-W55110 = 550×1100 mm, so you can match the machine to your mold size.
Can shot volume and stroke be customized?
Yes. Shot volume is configurable at 10 / 35 / 70 / 160 / 285 g, and opening strokes and ranges can be further customized to the application.
Do you provide LSR molds for this machine?
Yes. TYM designs and manufactures custom liquid silicone molds and cold-runner systems matched to the TYM-W Series.
Can the machine be integrated with automation?
Yes. The TYM-W Series supports robotic loading, automated demolding, vision inspection, and complete turnkey production lines for high-volume manufacturing.
