Howly Screw / Zhoushan Howly Plastic Machinery is a plastic machinery components manufacturer based in Zhoushan, Zhejiang. Its main products are screw barrels for injection molding machines, extruders, and rubber machinery, with related offerings including gearboxes, heaters, blowers, die heads, and spare parts for plastic machinery. The website is not a typical online e-commerce store; it is a B2B manufacturer inquiry site where users discuss requirements via Inquiry, Get A Quote, email, phone, WhatsApp, or online chat.
Based on the indexed content, its product range covers single screws, parallel twin screws, conical twin screws, bimetallic barrels, rubber extruder screws, and more for the plastics and rubber industries. The pages list various process and material details, including 38CrMoAlA, 42CrMo, SKD11, SKD61, duplex stainless steel, as well as nitriding, hard chrome plating, bimetallic spraying/centrifugal casting, and other treatments. Some product pages provide parameters such as nitrided layer depth, hardness, surface roughness, and straightness, which are useful for engineering procurement evaluation.
The site does not publish prices, MOQ, payment methods, or shipping terms, making it a typical quote-based supplier site. Some conical twin screw pages mention customization according to customer requirements, a 30-day production time, and a 1-year warranty. There is also wording about the “fastest delivery time,” but without specific lead times or international shipping arrangements. Service channels are relatively plentiful, including phone, WhatsApp, email, and LiveChat, with 7/7 availability noted, so communication convenience is acceptable.
The advantages are its focused product categories and clear industrial positioning, making it suitable for specification-based purchasing and customization. Its technical parameter disclosure is more detailed than that of ordinary brochure-style sites, and the multilingual pages indicate an export-oriented focus. The drawbacks are also obvious: the website has repetitive content, spelling issues in the English copy, and lacks information on certifications, customer cases, testing equipment, production capacity, and quality management systems. Pricing, payment, and logistics information are absent, so transaction transparency is limited.
It is better suited to plastic machinery manufacturers, processing plants, repair companies, and industrial goods trading firms conducting preliminary supplier screening or spare parts inquiries. It is not ideal for small e-commerce sellers who want online price comparison and instant ordering. Access from China should work directly; payment methods are not disclosed. If platform escrow or broader supplier comparison is needed, buyers can also check Alibaba.com, Made-in-China, Global Sources, and other Zhoushan screw barrel manufacturers.
