Changzhou Hongxinyutai Precision Mold Co., Ltd. is a dedicated manufacturer of high-precision injection molds, and we are proud to present our Injection Mold for Thick-Wall Compact components. This mold is engineered with hardened S136 steel, a hot runner system, and a mirror polish finish to deliver superior performance for demanding applications. With a proven lifespan of 300,000 shots and full compliance with IATF 16949:2016 quality management standards, this mold is the ideal solution for producing thick-walled parts with exceptional surface quality and dimensional stability.
Key Features & Technical Specifications
- Premium Material – Hardened S136 Steel: S136 is a high-grade stainless steel with excellent corrosion resistance, high hardness (HRC 48-52 after hardening), and outstanding wear resistance. This ensures minimal deformation and consistent performance over hundreds of thousands of cycles.
- Hot Runner System: The integrated hot runner reduces material waste, shortens cycle times, and eliminates the need for secondary degating. It provides precise temperature control for uniform melt flow, especially critical for thick-wall parts to avoid sink marks and voids.
- Mirror Polish Surface Finish: Achieved through a multi-step polishing process, the mirror finish (SPI A1 level) ensures a flawless cavity surface. This imparts a high-gloss, scratch-free appearance to the molded parts and facilitates easy part ejection.
- 300,000 Shots Lifespan: Designed and tested for 300,000 injection cycles under normal operating conditions, this mold offers a long service life with low maintenance requirements, making it a cost-effective investment.
- IATF 16949:2016 Certified: Our mold manufacturing process follows the stringent automotive quality management system, ensuring traceability, process control, and continuous improvement. This certification is a guarantee of reliability and consistency.

Frequently Asked Questions (FAQ)
Q1: What is the typical lead time for this mold?
A: The lead time depends on mold complexity and current production schedule. Typically, it ranges from 25 to 45 working days. We can expedite for urgent orders upon request.
Q2: Can you customize the hot runner system (valve gate vs. open gate)?
A: Yes, we offer both valve gate and open gate hot runner options based on your part geometry and material. We will recommend the most suitable solution.
Q3: Is the mold suitable for high-temperature engineering plastics?
A: Yes, hardened S136 steel can withstand temperatures up to 300°C, making it suitable for materials like PC, ABS, Nylon, POM, and even some filled plastics. We can also adjust thermal control accordingly.
Q4: How do you ensure the mirror polish quality?
A: We use a multi-step polishing process with diamond pastes, achieving SPI A1 standard. The surface roughness is verified with a profilometer to ensure Ra ≤ 0.05 µm.
Q5: What maintenance is required after 300,000 shots?
A: After reaching the expected lifespan, we recommend a thorough inspection of cavity surfaces, hot runner tips, and cooling channels. Routine maintenance such as cleaning and light polishing can extend the mold’s life further.
Q6: Do you provide mold trial and sample parts?
A: Yes, we offer T1 (first trial) service at our facility. Samples can be shipped for customer approval before mass production. A detailed mold trial report is provided.
Q7: What payment terms do you accept?
A: We typically accept T/T, L/C, and other negotiable terms. A 30% deposit is required to start production, with the balance due before shipment.
Q8: Can you supply spare parts (e.g., cavity inserts, hot runner nozzles)?
A: Absolutely. We manufacture spare parts upon request and keep design files on file for rapid reproduction.
