Common Problems in LSR Injection Mold Projects
Many OEM buyers and engineers face unstable production, high defect rates, and poor tooling performance when working with inexperienced LSR mold suppliers.
Most issues are not caused by the silicone material itself, but by poor mold design, improper venting, and lack of process understanding.
⚠️ Typical Problems in LSR Mold Production
- Excessive flash on silicone parts
- Dimensional variation between batches
- Air traps caused by poor venting design
- Unstable cold runner temperature control
- Short mold life in high-volume production
- Difficult demolding for complex geometries
- High material waste due to runner imbalance
- Inconsistent cavity pressure in multi-cavity molds
- Long debugging time during mold trial (T0/T1 delays)
❓ Why These Problems Happen
In most cases, LSR molding issues are not "production problems", but mold engineering problems. Key root causes include:
- Improper cold runner system design
- Lack of DFM optimization before tooling
- Incorrect gate and vent positioning
- Insufficient understanding of LSR flow behavior
- Weak tolerance control in precision tooling
- No Moldflow or simulation support during design stage

Frequently Asked Questions About LSR Mold Manufacturing
The optimal mold structure depends on part geometry, tolerance requirements, and production volume. Common options include cold runner and hot runner systems, with cold runner being the most widely used for stable and cost-efficient production.
Flash prevention is achieved through precise parting line design, controlled cavity sealing, optimized clamping force, and proper venting structure to maintain balance during injection.
Cold runner molds keep the material unheated in the runner system, while hot runner systems use temperature-controlled manifolds for precise material distribution and reduced waste in high-volume production.
Key factors include part geometry, number of cavities, sealing requirements, venting strategy, and tolerance level. More complex parts require advanced gating and venting control.
Cavity balance is controlled through symmetrical layout design, optimized runner length, and consistent gate sizing to ensure uniform material flow and curing across all cavities.
Common materials include hardened steel for high-volume production and aluminum for prototype or short-run molds, depending on durability and thermal stability requirements.
Proper venting allows trapped air to escape during injection, preventing defects such as air traps, incomplete filling, and surface imperfections.
Dimensional instability is usually related to uneven cavity pressure, improper mold temperature control, or insufficient structural rigidity in the mold design.Dimensional instability is usually related to uneven cavity pressure, improper mold temperature control, or insufficient structural rigidity in the mold design.
Key evaluation points include mold design capability, experience with LSR-specific tooling, ability to control flash risk, transparency in engineering decisions, and support during trial runs.
