Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, leverages a 1,000–3,000 square meter factory and a skilled team of 51–100 employees to deliver high-quality tooling solutions. Our Smart Door Lock Plastic Injection Mould is engineered with premium S136 steel and a 1x4 hot runner system, ensuring exceptional precision, durability, and efficiency for mass production of smart lock components. With TS16969 certification and a global export footprint covering North America, Europe, Asia, and beyond, we are your trusted partner for reliable, high-performance molds.
This mold is specifically designed for the demanding requirements of smart door lock manufacturing, where tight tolerances, consistent part quality, and long tool life are critical. The combination of S136 steel (known for its corrosion resistance and high polishability) and a 1x4 hot runner (which reduces waste and cycle time) makes it an ideal solution for producing intricate plastic parts with smooth surfaces and minimal defects.
Key Features & Benefits
- S136 Steel Construction: Offers excellent corrosion resistance, high hardness (up to 48-52 HRC), and superb mirror polish capability, resulting in molds that withstand aggressive plastics and maintain surface finish over millions of cycles.
- 1x4 Hot Runner System: Reduces material waste by eliminating cold runners, shortens cycle times by 20-30%, and improves part consistency through precise temperature control. Each nozzle is independently controlled for balanced filling.
- High-Precision Machining: Achieves dimensional accuracy within ±0.01mm, ensuring that smart lock components fit perfectly and function reliably.
- Optimized Cooling Design: Conformal cooling channels (optional) accelerate heat dissipation, reducing cycle time and minimizing warpage.
- Durable Mold Base: Standard S50C steel or custom grades (e.g., 718H) are available, with hardened guide pins and bushings for long service life.
- TS16969 Certified Process: Our quality management system ensures consistent production, traceability, and continuous improvement – ideal for automotive-grade smart lock components.
- Customizable Cavity Count: While the standard is 1x4 (single cavity with 4 hot drops), we can design multi-cavity layouts (2x2, 1x8, etc.) based on your production volume requirements.

Our smart door lock mold is designed to process a wide range of engineering plastics, including ABS, PC, PC/ABS, POM, and PA6+GF. The hot runner system minimizes material waste, making it an environmentally friendly and cost-effective solution. With optimized gate locations and venting, we ensure that even complex geometries (e.g., thin walls, snap fits, and internal slides) are filled without voids or flash.
FAQ – Frequently Asked Questions
-
Q: What is the typical lead time for this mold?
A: Usually 30–45 working days, depending on complexity and current workload. We offer expedited service for urgent orders. -
Q: Can you customize the mold for different lock designs?
A: Yes, we provide full customization. Send us your 3D part file (STEP/IGS) and we will engineer the mold accordingly. -
Q: What is the advantage of S136 steel over regular P20?
A: S136 offers superior corrosion resistance, higher hardness, and better polishability, making it ideal for clear or glossy parts and for molding corrosive plastics like PVC. -
Q: How does the 1x4 hot runner improve production efficiency?
A: It eliminates cold runner waste, reduces cycle time, and allows for precise temperature control at each cavity, leading to higher yield and lower per-part cost. -
Q: Do you offer mold trial and testing before shipment?
A: Absolutely. We conduct full mold trials on-site, provide sample parts, and make adjustments to ensure the mold runs perfectly. -
Q: Is the mold compatible with all injection molding machines?
A: We design the mold base and clamping plates to match your machine specifications (e.g., tie bar distance, ejector pattern). Please provide machine details. -
Q: What warranty do you provide?
A: We offer a 12-month warranty on workmanship and materials, covering defects under normal use. -
Q: How do you ensure the mold quality?
A: Our TS16969-certified quality system includes incoming material inspection, in-process checks, CMM dimensional verification, and final test-run reports.
