Product Description
Our factory offers plastic mould tooling support for bottle caps and liquid packaging plastic components. For many packaging buyers, tooling is the starting point of product stability. A good mold tool should not only produce a qualified sample, but also support long-term production with stable dimensions, controlled defects, and efficient output. Our plastic mould tooling service is especially suitable for bottle caps, dispensing caps, double-opening caps, vented caps, and customized closure structures used in liquid container packaging.
We work from technical drawings, prototypes, existing cap samples, or container matching requirements. During plastic mould tooling development, we consider the final production environment, including injection material, cap thread, sealing surface, opening structure, mold durability, production automation, and inspection requirements. This practical approach helps customers reduce trial-and-error costs and move more smoothly from development to batch production. For agents and overseas buyers, it also means a more dependable supply chain when expanding packaging product lines.

Application Areas
Plastic Closure Manufacturing
Used for developing molds for bottle caps, dispensing caps, and customized plastic closures.
Liquid Packaging Projects
Suitable for edible oil, detergent, cleaning liquid, personal care, and selected chemical liquid packaging.
OEM Cap Development
Supports customers who need mold tooling based on drawings or physical prototypes.
Packaging Product Expansion
Useful for distributors and packaging companies developing new cap series for local markets.
Customization Capability
We support OEM processing and technical drawing-based production. Before starting tooling, we can review the cap's structure, function, bottle mouth compatibility, material requirements, and production feasibility. This step is important because a cap design that looks good on paper may still need adjustment for mass injection molding.
Custom sample development usually takes around 30-90 days. After sample confirmation, mass production can be arranged according to customer order plans. Our experience with liquid container caps allows us to provide more practical suggestions on thread matching, sealing design, venting, and pouring structures.
Factory Strength
Dongguan Shun chang plastic Products Co., Ltd has a 2,000㎡ production facility and a team with around 15 years of bottle cap-related experience. The company was established in 2017, and the core team has been developing liquid container plastic caps since 2010. Our patented product development history gives us strong practical understanding of tooling and production.
We have 6 bottle cap-related patents and a registered trademark. Our self-improved automatic production line supports product taking-out, inspection, defective product rejection, combination, and packing. This helps connect tooling development with actual production more efficiently.
After-Sales Service
We provide dedicated after-sales support for customer inquiries, production feedback, and quality-related issues. If goods arrive damaged or a confirmed quality issue occurs, we can provide replacement or compensation according to actual conditions. For long-term partners, we also collect use feedback and provide technical improvement suggestions when needed.
Our service process includes pre-sales consultation, production follow-up, and after-sales response. During production, photo and video updates can be provided so overseas customers can track project progress before shipment.
