As a professional manufacturer based in Changzhou, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in custom injection mold tooling for industrial chemical containers. Our Industrial Chemical Container Injection Mold is designed to produce high-quality plastic wide-mouth jars with screw caps, meeting the rigorous demands of the chemical packaging industry. With over 7 years of experience, a factory size of 1,000–3,000 square meters, and a dedicated team of 51–100 employees, we deliver precision molds that ensure consistent performance, long service life, and cost-effective production.
This mold is engineered to produce durable, leak-proof wide-mouth jars that are suitable for storing adhesives, solvents, paints, and other industrial chemicals. The screw cap design provides secure sealing, while the injection mold itself is built with robust steel materials and advanced cooling systems to maximize cycle efficiency. Our molds are fully customizable from cavity count to surface finish, enabling you to achieve your exact production requirements.
At Changzhou Hongxinyutai, we understand that quality and reliability are non-negotiable in chemical packaging. That is why every mold undergoes strict quality control and is backed by our TS16969 certified manufacturing process. We serve clients across North America, South America, Europe, Asia, Africa, and Oceania, and we are ready to support your next project with tailored OEM tooling solutions.
Key Features & Technical Specifications
- Precision Cavity Design: Multi-cavity options (1–8 cavities) to balance output speed with mold cost. Each cavity is machined with CNC and EDM for tight tolerances.
- High-Quality Steel Selection: Choose from P20, H13, 718H, or S136 depending on production volume and chemical resistance requirements. All steels are sourced from reputable mills.
- Advanced Cooling System: Optimized water channels reduce cycle time by up to 15%, ensuring faster production and lower energy consumption.
- Hot Runner or Cold Runner: Hot runner systems (e.g., YUDO, HASCO) minimize waste and improve fill consistency; cold runner is available for simpler designs.
- Durable Screw Cap Molding: The mold includes a thread release mechanism (collapsible core or unscrewing) to produce precise internal threads for secure capping.
- Versatile Material Compatibility: Suitable for PP, HDPE, LDPE, PET, and other thermoplastics commonly used in chemical containers.
- Surface Finish Options: SPI A2 (mirror) for clear jars, or textured finishes (C3) for improved grip and appearance.
- Mold Base Standard: LKM, HASCO, or DME standards ensure easy replacement and maintenance globally.

Frequently Asked Questions (FAQ)
1. What materials can you use for the mold and the jar?
The mold steel is typically P20 or H13, and the jar can be made from PP, HDPE, LDPE, PET, or other thermoplastics depending on your chemical compatibility requirements.
2. How long does it take to manufacture the mold?
The standard lead time is 25–45 working days, depending on cavity count, complexity, and current workload. We can prioritize urgent orders (subject to additional charges).
3. Can you produce a mold with 8 cavities for high-volume production?
Yes, we offer multi-cavity molds up to 8 cavities (or more with special design). We will recommend the optimal cavity number based on your target production volume and budget.
4. Do you provide samples for testing before mass production?
Yes, we provide trial shot samples (T1/T2) for your approval. The samples are shipped within 5–7 days after mold completion. Minor adjustments can be made if needed.
5. What is the mold warranty period?
We offer a 12-month warranty from the shipping date against defects in material and workmanship. Normal wear and tear are not covered.
6. Can you custom-design the jar shape and cap threading?
Absolutely. We accept OEM custom designs. Just provide your 2D/3D drawings or sample, and our engineers will assist with DFM (Design for Manufacturing) analysis.
7. How do you ensure the mold is suitable for chemical containers?
We design the mold with proper gate location, adequate venting, and robust cooling to avoid warpage. The steel selection can be upgraded to corrosion-resistant grades (e.g., S136) for aggressive chemicals.
8. Do you ship molds worldwide? What are the shipping terms?
Yes, we ship to all major markets. Common ports are Shanghai, Shenzhen, and Jiangsu. We can arrange FOB, CIF, or DDP terms. We also provide wooden crate packaging for safe transport.
