Edible Oil Cap Mold
High‑Precision Engineering
Manufactured with 5‑axis CNC machining, achieving dimensional accuracy of ±0.005 mm.
Cavities and cores are produced from high‑grade stainless steels such as ASSAB S136, Austrian M310, or 420 stainless steel, with vacuum heat treatment reaching HRC 50–55 to guarantee corrosion resistance for food‑grade applications.
Exceptional Mold Longevity
Standard service life exceeds 5 million shots; with premium coatings (e.g., DLC), life can extend to 10 million shots.
Critical components (cavities, cores, hot‑runner manifolds) use wear‑resistant materials like Japan DC11, Austrian W302, or US H13 (hardness up to HRC 60–64), ensuring 5–10 years of reliable operation under proper maintenance.
Edible Oil Bottle Cap Mold
Product Overview
The edible oil bottle cap mold is a premium injection molding tool engineered specifically for producing caps and closures for edible oils – including olive, sunflower, soybean, and palm oil. Unlike standard beverage closures, edible oil caps require superior leak‑proof sealing, excellent resistance to grease and corrosion, and often integrate special features such as pull‑rings and tamper‑evident bands. Our molds are built with high‑grade steel and advanced hot‑runner systems to guarantee consistent part quality in high‑volume production.

Identification & Traceability Systems
Our edible oil cap molds are fully equipped with comprehensive product identification and traceability features:
- Brand Logo (Logotype) – custom logos, text, and graphics are directly molded onto the cap surface for a strong brand presence.
- Date Stamp – a replaceable year/month date marking system enables easy batch traceability.
- Interchangeable Cavity Inserts – cavities can be quickly swapped to change the cap’s identification details without affecting the overall mold structure.
- Surface Finish Options – high‑gloss polishing or MT standard textures are available to meet diverse brand appearance requirements.
Applications
Our molds are widely used in the production of caps for various edible oil packaging:
- Olive oil bottles – high‑end caps often integrate a pouring spout and drip‑less design; sometimes 4‑cavity molds with each cavity tailored for a different shape.
- Sunflower oil bottles – standard screw caps with emphasis on sealing performance and easy opening.
- Soybean / vegetable oil bottles – caps with side protrusions, grooves, and internal threads; high‑volume production uses multi‑cavity molds.
- Palm oil containers – suitable for large‑capacity packaging (5 L, 10 L, 20 L, 25 L) where sturdy, secure closures are essential.
Supported cap types include screw caps, tamper‑evident caps, pull‑ring caps, flip‑top caps, and combination closures.
