Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of rotary cutting die inner frame cutter knife in China. If you're going to wholesale bulk cost-effective rotary cutting die inner frame cutter knife made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
A worn or out-of-tolerance inner frame cutter knife is one of the fastest routes to misaligned foil, jagged cuts, and unplanned downtime on your HLP2 or HLP180 line. This replacement knife is precision-ground on CNC equipment to a dimensional tolerance of ±0.005 mm, ensuring a consistent OEM-compatible fit and repeatable cut quality from the first cycle. Made from high-performance alloy steel with a multi-stage heat treatment and anti-wear surface coating, it is engineered to maintain blade sharpness through extended high-frequency production runs.

Manufacturing process
CNC precision forming
The knife body is machined on multi-axis CNC turning and milling centers to a dimensional tolerance of ±0.005 mm, ensuring guaranteed OEM-compatible fit with HLP2 / HLP180 tooling.
Super-mirror cutting edge
The cutting edge is finished on dedicated ultra-precision grinding and polishing equipment, achieving a surface tolerance of ±0.002 mm.
Wire EDM contour cutting
Complex profile features are cut using a Seibu M50B Wire EDM machine, delivering sub-micron contour accuracy.
Multi-stage heat treatment
Each knife undergoes quench and temper heat treatment to optimize the balance of surface hardness and core toughness.
Quality control before shipment
Dimensional check - all critical dimensions verified against drawing tolerances
Hardness test - Rockwell hardness confirmed within specified HRC range
Edge integrity inspection - cutting edge examined for burrs, chips or surface defects
Fit verification - test-fit against reference tooling block before packing
Why Choose Us?
Direct dimensional interchangeability
The knife is engineered to the same functional envelope as the original Molins spare, not a loose approximation of it. Our CNC tolerance of ±0.005 mm on all critical dimensions means the knife seats into your machine without shimming, adjustment, or re-qualification.
Customization without minimum order penalty
If your line runs a non-standard paper thickness or your machine has been re-tooled, we will machine to your drawing. Our CNC and Wire EDM capability supports custom blade geometry, bore diameter, or profile angle at low minimum order quantities.
FAQ
Q: Is this knife a direct OEM replacement for the Molins HLP2 and HLP180?
A: Yes. We manufacture strictly according to your drawings, ensuring that all critical mounting and cutting dimensions are precision-machined.
Q: What is the recommended replacement interval for the inner frame cutter knife?
A: Replacement frequency depends on paper type, line speed, and production volume. A worn knife typically shows itself through ragged cut edges, increased paper dust, or rising trim-waste percentage - any of these signals it is time to replace.
Q: Can Hansheng supply a knife to my own drawing or modified dimensions?
A: Yes. We accept customer drawings for customized variants. Our in-house CNC turning, milling, and Seibu Wire EDM capability allows us to hold tolerances as tight as ±0.002 mm on surface-critical features. Please send your drawing to marketing@hansmat.com for a quotation.
Q: How long is the lead time?
A: Custom orders require approximately 10–15 business days depending on specification complexity and number.
Q: Does Hansheng supply other spare parts for the HLP2 / HLP180 line?
A: Yes. Our cigarette machine spare parts range includes filter rod cut-off knives, garniture tongue pieces, tungsten carbide cork knives, grinding wheels, and more. If a part you need is not listed, contact us - we can often manufacture to drawing.
