Transparent Wide-Mouth Jar Molds: Precision Tooling for Clear Container Production
ZSM Machinery proudly presents our Transparent Wide-Mouth Jar Molds—precision-engineered tooling solutions designed specifically for the production of high-clarity wide-mouth containers. Wide-mouth jars are essential packaging for food products, cosmetics, pharmaceuticals, and household items, offering easy access and convenient filling . Our transparent jar molds deliver exceptional optical clarity, dimensional precision, and reliable performance for manufacturers serving these diverse markets.
Understanding Wide-Mouth Jar Applications
Wide-mouth jars feature larger neck openings than standard bottles, making them ideal for products requiring easy access, scooping, or filling . The transparent nature of these containers allows consumers to view the product inside, making clarity a critical quality attribute .
Key Applications:
Food Packaging: Jars for honey, jams, sauces, pickles, and dry foods
Cosmetics and Personal Care: Cream jars, lotion containers, and beauty product packaging
Pharmaceuticals: Medical jars, vitamin containers, and healthcare packaging
Household Products: Storage containers for various household items
Key Features of ZSM Wide-Mouth Jar Molds
1. Superior Optical Clarity
Our transparent jar molds are engineered to maximize clarity:
Mirror-polished cavity surfaces ensuring exceptional transparency in finished jars
Optimized cooling design preventing stress-induced haze or crystallization
Precision temperature control maintaining optimal material properties for clarity
Surface finish options from high-gloss to custom textures as required
2. Precision Wide-Mouth Neck Finishes
The neck finish is critical for jar functionality and sealing performance:
Neck sizes from 38mm to 120mm and beyond for various applications
Thread or snap-on configurations compatible with standard closures
Tamper-evident features integrated into neck design
Custom neck finishes for proprietary closure systems
3. Advanced Hot Runner Systems
Our wide-mouth jar molds feature state-of-the-art hot runner technology:
Individual temperature control for each nozzle, maintaining accuracy within ±1°C
Valve gate design providing clean gate vestige with no tail trimming required
Balanced filling across all cavities ensuring consistent jar weight and dimensions
Optimized for PET processing with low acetaldehyde (AA) generation
4. Premium Material Construction
| Component | Material | Hardness |
|---|---|---|
| Core and Cavity Inserts | S136 Stainless Steel | HRC 46-50 |
| Neck Rings | S136 / Nitrided Steel | HRC 43-52 |
| Mold Base | P20 / 4Cr13 | Pre-hardened |
| Hot Runner Components | H13 Tool Steel | Heat-treated |
