Custom Blow Mold Cases Tailored to Your Needs

In the world of protective packaging, the blow mold case has emerged as a premier solution for safeguarding valuable equipment across industries. Unlike injection molding, which is ideal for small, intricate parts, blow molding excels at creating hollow, seamless, and durable enclosures with uniform wall thickness. This process involves inflating a heated plastic parison inside a mold, resulting in a one-piece case with exceptional structural integrity. The blow mold case is particularly valued for its ability to absorb impact, resist chemicals, and withstand extreme temperatures, making it indispensable for automotive, medical, military, and industrial applications. At Changzhou Pengheng Auto Parts Co., Ltd., we have refined this technology since 2007. Our three production bases and 26 blow molding machines enable us to produce over 5 million sets annually, catering to clients worldwide.

Frequently Questions

What is a blow mold case and how is it different from other cases?

A blow mold case is a protective enclosure manufactured using the blow molding process, where a heated plastic tube is inflated inside a mold to form a hollow, seamless shape. Unlike injection-molded cases, which are typically made in two or more pieces and assembled, blow-molded cases are created as a single, continuous piece, offering superior structural integrity and impact resistance. This makes them ideal for rugged applications. Additionally, blow molding is cost-effective for large, hollow parts, allowing for complex shapes and uniform wall thickness. Our blow mold cases are custom-designed to meet your specific requirements, ensuring a perfect fit for your equipment.
Absolutely. Customization is at the core of our service. We offer extensive customization options for size, shape, color, material, and features. You can choose from a wide range of colors to match your brand, and we can incorporate logos, text, or graphics through printing or embossing. Additional features such as handles, latches, hinges, wheels, and foam inserts are available. Our engineering team will work with you to design the perfect case for your needs, providing 3D renderings and prototypes for approval before mass production.
We use high-quality thermoplastics including HDPE, ABS, PP, and PC, selected based on your application’s requirements. These materials are known for their strength, impact resistance, and durability. HDPE offers excellent chemical resistance, while ABS provides a good balance of toughness and aesthetics. PC is highly impact-resistant and transparent. Our cases undergo rigorous testing to ensure they withstand drops, impacts, and environmental stressors. With proper use, our blow mold cases can last for many years.
Lead time varies depending on the complexity of the design and order quantity. Typically, for a new custom project, the timeline includes design approval (1-2 weeks), mold making (3-4 weeks), and production (2-4 weeks). For repeat orders, production can be as quick as 2-3 weeks. We strive to meet your deadlines and offer expedited services if needed. Our global production network allows us to optimize scheduling and minimize delays.
Yes, we ship worldwide. We have extensive experience in international logistics and can arrange shipping via sea, air, or express courier based on your preference and urgency. We offer various Incoterms including FOB, CIF, and DDP. Our team will handle all necessary export documentation and ensure compliance with your country’s import regulations. We also provide tracking and updates throughout the shipping process.
