Founded in 2017, Changzhou Hongxinyutai Precision Mold Co., Ltd. is a specialized manufacturer with a 1,000–3,000 m² factory and a skilled team of 51–100 employees. We are proud to present the PP-T30 Breather Valve Plastic Mold, designed specifically for automotive engine crankcase ventilation systems. This mold delivers exceptional precision and durability, ensuring consistent production of breather valve components that meet the rigorous demands of modern engines. With our TS16969-certified processes and global export experience to markets including North America, Europe, and Southeast Asia, we offer a reliable solution for OEMs and aftermarket suppliers.
The PP-T30 mold is engineered to produce breather valves that control pressure and oil vapor recirculation within the crankcase, preventing oil leaks and reducing emissions. Our mold features advanced cooling channel design and optimized gate placement, resulting in shorter cycle times and higher part quality. Whether you need a single-cavity prototype or a multi-cavity high-volume tool, we provide customized solutions tailored to your exact specifications.
Key Features & Technical Specifications
- Material Compatibility: Optimized for PP-T30 resin, but also suitable for similar polypropylene grades with minimal adjustments.
- High Precision Tolerances: Maintains ±0.02mm tolerance on critical sealing surfaces, ensuring leak-proof operation.
- Robust Construction: Made from premium tool steel (e.g., 2316, 2344) with heat treatment and nitriding for extended mold life.
- Efficient Cooling System: Conformal cooling channels reduce cycle time by up to 15% compared to standard designs.
- Easy Maintenance: Modular design with quick-change inserts minimizes downtime for cavity replacement or cleaning.
- Compliance with Industry Standards: Manufactured under TS16969 quality management system, ensuring consistent output.
- Flexible Cavity Number: Available from 1 to 16 cavities, depending on production volume requirements.
- Customizable Ejection System: Hydraulic, pneumatic, or mechanical ejection options to suit your molding machine.

Frequently Asked Questions
-
What is the typical lead time for the PP-T30 mold?
Lead time depends on complexity and cavity count. For a standard single-cavity mold, it is approximately 30–45 days. Multi-cavity molds may require 50–60 days. We can expedite for urgent orders upon request. -
Can the mold be used with other polypropylene grades?
Yes, the mold is designed for PP-T30 but can be adapted for other PP grades with similar shrinkage rates. We recommend discussing your specific material with our engineers to ensure optimal performance. -
Do you provide mold trial and sample parts?
Absolutely. We offer trial shots at our factory and will send you sample parts for approval before shipping. We can also provide video records of the trial process. -
What is the warranty period for the mold?
We provide a 12-month warranty against manufacturing defects on the mold base and cavity steel. Normal wear and tear are excluded. We also offer extended warranty options. -
Can you customize the mold for a specific injection molding machine?
Yes, we require the machine specifications (clamping force, tie-bar distance, locating ring size, etc.) and we will design the mold base accordingly. We are compatible with Haitian, Engel, Demag, and other common brands. -
How do you ensure the breather valve meets automotive emission standards?
Our mold design incorporates precise sealing areas and tolerances to ensure the final part achieves correct pressure regulation. The part can be tested per customer requirements, and we can adjust the mold design for specific performance targets. -
What is the minimum order quantity (MOQ) for this mold?
MOQ is 1 set. For custom molds, we accept single-piece orders. For production of plastic parts, MOQ can be discussed based on your annual volume. -
Do you provide mold maintenance services?
Yes, we offer maintenance packages including cleaning, coating, and repair. We can also provide spare parts like ejector pins, springs, and inserts.
