Are you seeking a reliable partner to manufacture high-quality stainless steel garlic presses that meet your brand’s exacting standards? At Topmetalstamping, we specialize in precision metal stamping, deep drawing, and finishing processes that transform raw stainless steel into durable, ergonomic kitchen tools. In this post, we’ll guide you through each step of the production and customization journey—from material selection and stamping to polishing, assembly, and branding—while addressing the top concerns our customers often raise and explaining how we consistently solve them.
1. Material Selection: The Foundation of Durability and Food Safety
Why Stainless Steel?
Stainless steel is the material of choice for garlic presses thanks to its corrosion resistance, strength, and hygienic properties. Grades like 304 and 316 stainless steel offer excellent resistance to acidic garlic compounds and repeated wash cycles.
Customer Concern: “How do I ensure food-grade quality and longevity?”
Our Solution: We source ASTM-certified 304 and 316 stainless steel coils from major mills, providing full mill test reports (MTRs) to guarantee composition and mechanical properties. This ensures your garlic presses remain rust-free and food-safe over years of use.
2. Precision Stamping & Deep Drawing: Shaping the Components
Progressive Stamping for Handles and Cups
Using progressive stamping dies, we form handle blanks, pivot housings, and perforated inner cups in one continuous strip—performing cutting, bending, and piercing in sequential stations.
Deep Drawing for the Press Cup
The garlic cup (the chamber that holds cloves) requires deep drawing to create a smooth, seamless cavity. We employ a multi-stage drawing process with intermediate annealing to prevent work-hardening cracks.
Customer Concern: “How do you avoid burrs, misalignment, or cracks?”
Our Solution:
- High-Precision Tooling: We use H13 tool steel with PVD coating for long die life and tight tolerances.
- In-Line Quality Checks: Automated vision systems verify hole patterns on the cup and handle alignment at each station.
- Process Parameters: Accurate control of draw ratios, blank holder force, and lubrication prevents tears and ensures uniform wall thickness.
3. Secondary Operations: Trimming, Deburring, and Welding
Trimming & Burr Removal
After stamping and drawing, each part undergoes laser trimming or fine blanking to remove flash. Precision robotic brushes and pneumatic deburring stations then eliminate any remaining burrs.
Assembly & Joining
For multi-piece presses, such as those with hinged handles, we use resistance spot welding or riveting with stainless steel pins to ensure robust, maintenance-free joints.
Customer Concern: “Can I avoid rattles, uneven movement, or weak joints?”
Our Solution: We calibrate welding parameters—current, time, pressure—to achieve consistent weld nugget strength without distorting the thin sheet. Rivets are torqued to spec, and assemblies are tested for smooth pivot action and absence of play.
4. Surface Finishing: Achieving the Perfect Shine
Polishing & Brushing
A bright, mirror-like finish or attractive brushed look enhances both aesthetics and cleanability. We offer multiple Learah finishes:
- Electropolishing: Removes micro-burrs, passivates the steel for superior corrosion resistance, and produces a hygienic, easy-to-clean surface.
- Mechanical Polishing & Brushing: Creates consistent grain patterns for a modern industrial look.
Customer Concern: “How do I ensure scratch resistance and uniform finish?”
Our Solution: We combine multi-stage polishing—coarse to fine grits—with controlled brush patterns. Every batch is measured for surface roughness (Ra) target of ≤ 0.4 µm. Random sample inspections under 5× magnification ensure consistent finish across parts.
5. Customization: Logos, Colors, and Packaging
Laser Engraving & Etching
For permanent branding, we use fiber laser engraving to mark logos, model numbers, or user instructions directly onto steel surfaces without affecting material integrity.
PVD Coatings & Color Accents
Need a gold-color press or vibrant handle accents? Our PVD (Physical Vapor Deposition) lines deposit wear-resistant, decorative films in a rainbow of hues—ensuring both durability and brand differentiation.
Packaging & Bulk Labeling
Custom blister packs, branded boxes, or bulk packs with UPC labels—our in-house packaging team handles design, prototyping, and fulfillment. We also integrate RFID tags or serialized QR codes for traceability if required.
Customer Concern: “How do I maintain branding quality and avoid peeling or fading?”
Our Solution: PVD coatings adhere at the molecular level, resisting scratches and dishwasher cycles. Laser engraving penetrates the metal, ensuring logos never wear off. And all packaging materials comply with FDA food-contact and recyclability standards.
6. Quality Assurance: Rigorous Testing and Certifications
Dimensional & Functional Checks
Every garlic press is checked for critical dimensions—cup diameter, handle clearance, and pivot tolerance—using CMM (Coordinate Measuring Machines). Functional tests simulate up to 10,000 press cycles to confirm hinge durability and consistent pressing force.
Corrosion & Cleanliness Testing
Parts pass salt spray (ASTM B117) and acid challenge tests to validate corrosion resistance. We also perform ATP swab and TOC tests on random samples to verify cleaning efficacy and absence of residual oils or contaminants.
Certifications & Traceability
Our facility is ISO 9001 and IATF 16949 certified. Each production lot is fully traceable via batch numbers tracked in our ERP system, ensuring accountability and rapid recall capability if ever needed.
