Our Capsule Molding Pin Plate is a precision-engineered core component for the automated production of hard gelatin and HPMC capsules. Manufactured from high-grade 316L stainless steel (or food-grade 304 stainless steel, customizable), each pin is precision-machined and polished to a mirror finish, ensuring consistent capsule wall thickness, smooth surface quality, and long service life. Designed to fit seamlessly with major capsule manufacturing lines, it is the foundational tool for producing high-quality empty hard capsules.

Capsule Molding Pin Plate Core Features & Advantages
Precision Machining: CNC-machined pins ensure uniform wall thickness and consistent capsule dimensions, directly reducing rejection rates in downstream processes.
Hygienic Material: Food-grade stainless steel construction complies with GMP and pharmaceutical hygiene standards, preventing contamination and ensuring safe contact with capsule materials.
Durable & Wear-Resistant: Mirror-polished surface minimizes friction and wear, extending the service life of both the pin plate and the produced capsules.
Easy to Clean & Maintain: Modular design allows for quick disassembly and cleaning, reducing downtime between production batches and simplifying validation processes.
Customization Support: Fully customizable pin size, layout, and material to match specific capsule types and production line requirements.
Capsule Molding Pin Plate Applications
Production of empty hard gelatin capsules
Production of HPMC (hydroxypropyl methylcellulose) vegetarian capsules

Frequently Asked Questions (FAQ)
Q: What capsule sizes can this pin plate produce?
A: Our pin plates can be customized to produce all standard hard capsule sizes, from the largest 000# down to the smallest 5#, as well as specialty sizes for targeted formulations.
Q: How do I choose between 304 and 316L stainless steel?
A: 304 Stainless Steel: Cost-effective, suitable for standard gelatin capsule production in non-corrosive environments.
316L Stainless Steel: Superior corrosion resistance, ideal for HPMC capsules, acidic formulations, or cleanrooms with strict hygiene requirements. We recommend 316L for pharmaceutical-grade production.
Q: How long is the typical service life of the pin plate?
A: With proper cleaning, lubrication, and storage, our pin plates can last for 50,000+ production cycles. Wear will depend on production frequency and material compatibility; we offer re-polishing and reconditioning services to extend service life.
