HCR Solid Silicone Injection Molding Machine for Keypads, Sleeves and Waterproof Parts
For silicone keypads, sleeves, waterproof plugs, baby-care parts or precision silicone components, HCR is the machine to review when the customer needs clean demolding, controlled color, low flash and repeatable shot control.
For these silicone products, customer value comes from matching shot accuracy, mold temperature, curing, demolding and cleanliness in one machine. Han Chang configures HCR around the actual silicone grade, mold layout, color requirement and target output.
Key HCR production advantages
- Shot accuracy is matched with silicone grade, part thickness and cavity count to keep multi-cavity weight and appearance consistent.
- Mold-temperature control and curing settings help protect color, surface feel, hardness and demolding quality for silicone appearance parts.
- Three-stage pressure and four-stage flow control let operators tune filling, packing and holding for thin sleeves, keypads or thicker grips.
- Clean demolding and handling are planned with the machine setup, which is important for food-grade, baby-care, medical and electronic silicone parts.
Machine Functions and Molding Control
For silicone products such as keypads, sleeves and waterproof plugs, the machine must control shot accuracy, mold temperature, curing time, clean demolding and handling quality at the same time. HCR is selected around the finished part standard, so precision silicone parts can keep color, surface quality and cavity-to-cavity weight under control.
The injection unit matches shot weight, runner layout and cavity count, helping silicone products avoid short shots, overpacking and uneven cavity weight.
Controlled mold temperature and curing time help reduce tacky surface, color shift, hardness variation and uneven part release. For rubber or solid-silicone parts, Han Chang matches material hardness, mold venting, platen temperature, holding time, vacuum, sliding-table or ejection needs and demolding method, giving the customer clearer control of sealing surface, flash, air marks and part removal.
Demolding direction, operator handling and trimming space are reviewed with the mold so appearance parts can leave the machine cleaner and with fewer surface marks.
HCR is configured around silicone grade, hardness, color requirement, mold temperature and demolding method, helping the customer control appearance quality and repeated output.
HCR model range for silicone parts
For precision silicone parts, small to medium shot weight, trial molds and lower cavity count.
For common silicone keypads, sleeves, plugs, medium molds and higher repeated production demand.
For larger silicone products, heavier molds, higher cavity count or stronger platen/daylight requirements.
Han Chang checks silicone grade, shot weight, mold temperature, cavity count, demolding direction and cleanliness requirement before recommending the HCR model.

How Han Chang matches HCR to silicone products
Han Chang starts from the finished silicone part: keypad feel, sleeve wall thickness, waterproof-plug sealing surface, color standard, mold temperature and how the operator removes the part. These details decide the HCR shot size, platen/daylight, heating control and demolding arrangement.
Food-grade, medical, baby-care and industrial silicone have different cleanliness and color-control requirements, so machine configuration starts from material grade.
Shot weight, runner layout, cavity count and part thickness decide whether each cavity receives enough material without flash or short shots.
Mold temperature, curing time and venting control surface tack, color shift, hardness and part release condition.
Demolding direction, trimming space, operator access and inspection flow are matched with the HCR machine action before increasing cavity count or automation.
- Part drawing with thickness, appearance surface, tolerance, color standard and trimming method.
- Solid silicone grade, Shore hardness, color requirement, feeding method and cleanliness requirement.
- Mold size, mold weight, cavity count, runner/gate layout, mold-temperature range and demolding direction.
- Trial record with shot weight, mold temperature, three-stage pressure, four-stage flow, curing time, color variation, demolding condition and machine alarms if any.
After-sales service, imported components and export support
Han Chang supports HCR customers through the full machine service cycle. Service support covers model selection, installation discussion, operating guidance, machine-status review, online technical diagnosis and replacement-part coordination.
Taiwan and Mainland China service teams can support customers by case. Applicable configurations can use imported key components such as Mitsubishi PLC, Fuji Electric touch panel and Japanese-brand oil seals, giving customers stronger confidence in control stability, maintenance judgment and long-term machine operation.
Han Chang can review injection-unit movement, mold-temperature control, PLC parameters, heating deviation, sensors, valves, oil seals and operation videos online, then guide machine adjustment or replacement-part coordination.
Mitsubishi PLC, Fuji Electric touch panel and Japanese-brand oil seals can be used in applicable configurations so operators have clearer parameter control and maintenance teams have a more stable replacement-part path.
When the machine has abnormal pressure, unstable injection, heating deviation, PLC alarm, clamping movement, oil-hydraulic action or sensor issues, Han Chang can review settings, photos and operation videos online before arranging parts or further service.
CE certification is available for export projects when required. Han Chang can coordinate the selected machine configuration, electrical specification and documentation scope so customers prepare export machine files more efficiently.
