Vacuum Compression Molding Machine | Precision Silicone Parts
Choose the HCAV / HCAVE vacuum compression molding machine when silicone or rubber parts need a clean surface, fewer bubbles and stable hot press curing.
The machine pulls air out through the vacuum chamber, then uses heated platens and oil-hydraulic pressure holding to keep the mold closed during curing. Han Chang configures the same machine series for rubber or silicone according to the compound, mold and demolding method.
Key machine advantages
- Vacuum chamber design removes trapped air before the part is fully pressed.
- Oil-hydraulic pressure holding keeps the mold closed during silicone curing or rubber vulcanization.
- Heating plate control helps the finished surface, hardness and low-bubble appearance stay consistent.
- HCAV / HCAVE models can be matched to different platen sizes, daylight and mold weights.
Machine Functions and Molding Control
The advantage of this machine is the combination of vacuum, heat and oil-hydraulic compression. Vacuum reduces air pockets; heated platens control curing; pressure holding keeps the mold closed so silicone and rubber parts can form with a more stable surface and sealing edge.
Vacuum removes air from the mold area before full pressure is applied, helping precision silicone and rubber parts reduce bubbles, voids and surface marks. 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.
Heating plate stability lets operators match silicone curing or rubber vulcanization time with the actual mold thickness and cavity layout.
Stable clamping and pressure holding help control flash, deformation and parting-line quality during repeated cycles.
The same machine series can be configured for rubber or silicone compression by matching compound behavior, mold venting and demolding method.
Model range and configuration
Suitable for precision parts, smaller molds and lower to medium platen demand.
Selected when mold size, cavity count, rubber/silicone weight or production output becomes higher.
Used when ejection support improves demolding stability or reduces operator damage to soft parts.
Confirm platen size, daylight, vacuum requirement, heating capacity, mold weight and demolding method.

Vacuum Compression Molding Machine | Precision Silicone Parts FAQ
Can the same vacuum compression machine process rubber and silicone?
Yes. The same HCAV / HCAVE machine series can be configured for rubber or silicone by matching compound behavior, mold design, vacuum requirement and curing conditions.
When should customers choose a vacuum type machine?
Choose HCAV / HCAVE when bubbles, air pockets, surface marks or sealing-edge defects are important production risks.
What is the difference between HCAV and HCAVE?
HCAV focuses on vacuum hot press compression. HCAVE adds ejection support when demolding stability or part removal needs more control.
What information helps Han Chang recommend the right model?
Prepare part drawings, material hardness, mold dimensions, cavity count, vacuum need, curing time, target output and factory layout.
