Custom Silicone Injection Molding Solution
Silicone parts are not easy to get right. Air bubbles, unstable dimensions, flashing, and inconsistent hardness are common issues, and we’ve seen all of them.
At Jiangzhi, we don’t just mold silicone. We help you get stable, production-ready parts that actually work in your application, whether it’s sealing, medical contact, or high-temperature environments. From mold design to process control, we handle the details that most suppliers overlook, so you don’t have to deal with problems later.
Silicone Injection Moulding Parameters Table
These parameters are carefully adjusted and verified during sampling to ensure stable dimensions and consistent part quality in production.
| Parameter | Recommended Range |
|---|---|
| Wall Thickness | 1.0mm – 5.0mm |
| Maximum Part Size | 300mm × 300mm |
| Minimum Feature Size | 0.5mm – 1mm |
| Tolerances | ±0.1mm – ±0.25mm |
Silicone Material Properties
- Stable performance under heat and pressure
- Long-term elasticity without deformation
- Chemical and environmental resistance
- Safe options for medical and food contact
| Property | Density | Tensile Strength | Flexural Strength | Impact Strength (Unnotched) | Heat Deflection Temp (0.45 MPa) |
|---|---|---|---|---|---|
| Value/Description | 1.02-1.05g/cm³ | 40 -50 MPa | 60-70 MPa | 20 -30 kJ/m² | 90-100℃ |
- The above parameters represent the baseline performance of the materials. Actual application should be dynamically optimized based on specific working conditions.

Jiangzhi Silicone Molding Parts are Guaranteed
No, we specialize in HTV (solid silicone) injection molding. HTV offers higher tear strength and better mechanical stability for many applications.
Yes, we offer medical- and food-grade silicone options. These materials are certified safe for skin and food contact.
Cracks often come from stress during cooling, poor mold design, or even using the wrong processing temps. We focus on balanced part design and proper molding conditions to keep your ABS parts crack-free.
Lead time for custom molds is about 2–4 weeks, while production runs can be completed in 7–15 days depending on order volume.
Silicone molding is ideal for flexible, heat-resistant, and biocompatible parts, while plastic injection molding is better suited for rigid, structural components. We can help determine the most suitable process and material based on your product’s requirements.
