OEM Clear Cosmetic Cap Injection: PMMA/AS, IATF 16949, Mirror Finish
Product Spotlights
As a professional manufacturer with years of injection molding expertise, Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our OEM Clear Cosmetic Cap Injection made from high-quality PMMA/AS materials. Our caps are designed to meet the stringent requirements of the cosmetic industry, offering a pristine mirror finish that enhances product shelf appeal. With our IATF 16949 (TS16969) certified production system, we ensure consistent quality, precision, and reliability for every batch. Whether you need a standard design or a fully customized solution, we are your trusted partner for premium cosmetic packaging components.
Product Overview & Key Features
- Material Excellence: Our caps are manufactured using PMMA (Polymethyl Methacrylate) and AS (Acrylonitrile Styrene) resin, known for their exceptional clarity, impact resistance, and dimensional stability. This material combination ensures the cap stays transparent and crack-free even under normal usage conditions.
- Mirror-Like Surface Finish: We employ advanced injection molding techniques and high-polish mold cavities to achieve a mirror finish on the cap surface. This high-gloss appearance gives your cosmetic product a luxurious, premium look that stands out on retail shelves.
- Precision Injection Molding: Our state-of-the-art injection molding machines, combined with tight process control, produce caps with consistent wall thickness, accurate dimensions, and zero burrs. This ensures a perfect seal and smooth operation with your bottle or jar.
- Custom OEM Service: We offer full customization from mold design to final production. You can specify the cap size, thread type, logo, color tint (if needed), and even add features like a flip-top or dispensing orifice. Our engineering team works closely with you to bring your vision to life.
- Certified Quality Management: Our factory operates under an IATF 16949 (TS16969) certified quality system. This means every step — from raw material inspection, molding parameters, to final packaging — is documented and controlled to meet international automotive and industrial standards. The result is a consistently defect-free product.
- Wide Application Range: Ideal for cosmetic bottles (lotion, cream, serum), perfume caps, nail polish caps, and essential oil dropper caps. The clear, glossy finish is especially suitable for high-end personal care products that require visual transparency.

Frequently Asked Questions (FAQ)
-
Q: Can you produce caps with a different material, like PET or polypropylene?
A: Yes, we can adapt our molds to process other materials such as PETG, PP, or SAN upon request. However, our standard PMMA/AS combination offers the best clarity and mirror finish. Custom material options are available — please consult our sales team. -
Q: What is the minimum order quantity (MOQ) for custom caps?
A: For new molds, MOQ is typically 10,000 pieces per design. For existing molds, MOQ can be as low as 5,000 pieces. We understand startups may need smaller volumes; contact us for flexible arrangements. -
Q: Do you provide free samples for evaluation?
A: Yes, we can provide existing stock samples free of charge (shipping cost applied). For custom-molded samples, a sample fee is required, which is refundable upon mass production order. -
Q: How do you ensure the mirror finish is free of scratches or flow lines?
A: We use high-polish mold steel (e.g., S136H) and precise injection parameters (melt temperature, injection speed, and cooling time) to minimize defects. Our quality inspection includes visual checks under controlled lighting and a gloss meter measurement. -
Q: Can you print or emboss our logo on the cap?
A: Absolutely. We support hot stamping, pad printing, laser engraving, and embossing/debossing. If you require a logo in the mold, we can modify the cavity accordingly. -
Q: What is the typical lead time for a new mold and first batch?
A: Mold fabrication: 20–35 days depending on complexity. First sample: 3–5 days after mold completion. Mass production: 15–25 working days after sample approval. -
Q: Does your factory have any environmental or sustainability certifications?
A: Our production complies with Chinese environmental regulations, and we can provide material safety data sheets (MSDS) and RoHS compliance reports. Specific sustainability certifications can be discussed on a project basis.
