China Hot Sale Powder Metallurgy Die for Lock Parts

In the lock manufacturing industry, the quality of powder metallurgy dies directly affects the quality and production efficiency of lock components. Lock parts have high requirements for dimensional stability, mechanical wear resistance, and appearance consistency. The powder metallurgy process has become an important production method in the lock industry due to its ability to achieve mass manufacturing of complex structures, high material utilization rate, and efficiency advantages. Common powder metallurgy lock components include lock cylinders, picking plates, rotors, positioning parts, and structural supporting components.

Our powder metallurgy dies focus on forming core components for civil locks, industrial locks, and smart locks, compatible with various lock parts such as lock cylinders, lock tongues, and lock bolts, covering stainless steel, iron-based, and copper-based powder materials. With high precision and high efficiency characteristics, the molds help manufacturers form complex-structured lock parts in one step, significantly reducing subsequent processing procedures, lowering manufacturing costs, and improving product consistency.

Low-price custom solutions. Our factory business includes designing, developing, and manufacturing powder metallurgy moulds, carbide parts, powder injection moulds, stamping toolings and precision mould parts.

Lock Part Powder Metallurgy Die Design and Machining

Molds commonly adopt multi-punch floating pressing structures to address the complex structure and fine dimensions of lock parts. For stainless steel lock bodies, molds are configured with upper punches, middle dies, fixed lower punches, and multiple floating lower punches, combined with mandrel components to achieve precise positioning and pressing through bridge seats and adjustment devices. The “one mold, double cavity” structure design effectively solves the problem of lower punch unilateral force tilting, improving production stability and efficiency.

Low-Cost Lock Part Powder Metallurgy Die Material Selection Optimization

The lock industry has characteristics of obvious mass production, multiple specifications and models, large dimensional variations, and high cost sensitivity. Therefore, mold development cycles, mold lifespan, and mold changeover costs significantly impact enterprise competitiveness. Powder metallurgy dies can greatly reduce secondary processing needs and improve capacity efficiency. Therefore, lock part mold materials can be selected from different cost steel grades according to customer requirements, meeting applications for both small batches and large volumes to achieve cost-saving choices, such as tungsten carbide, powder high-speed steel, bearing steel, tool steel, nickel-based superalloys, etc.

Locks are long-cycle consumer products with high reliability requirements. Selecting mature powder metallurgy die suppliers in mass production can reduce overall costs, improve consistency, and enhance product market performance. Our company is willing to become a stable supporting partner for the lock industry with customized processing services.

Powder Metallurgy Dies for Fasteners

Fasteners have extremely high demand in machinery, construction, home appliances, automotive, and tool industries, and their production process needs to balance batch consistency, dimensional tolerances, and assembly reliability. The powder metallurgy process has been widely applied in manufacturing nuts, bushings, positioning parts, self-locking structures, and special geometric parts due to its advantages of high material utilization rate, ability to form complex geometric structures, and suitability for mass manufacturing.

Powder metallurgy dies directly determine the dimensional consistency, density distribution, and forming accuracy of parts. Fasteners emphasize matching tolerances during assembly, so fastener powder metallurgy dies must balance pressing strength, demolding smoothness, and sintering shrinkage compensation design. If mold design is unreasonable, quality problems such as hole diameter deviation, thread profile distortion, or sintering deformation may occur.

Providing Fastener Powder Metallurgy Die Design and Machining Services

Molds adopt multi-punch combination structures and innovative demolding designs. Core components include upper punch sets, middle dies, lower punch sets, and mandrels. For nuts with internal threads, lateral core-pulling forming technology can be adopted, directly machining threads on the lower punch for one-step forming during pressing, eliminating turning operations and reducing manufacturing costs by reducing processes. For multi-stepped and thin-walled parts, mold design can optimize the integral forming upper punch into a combination of upper outer punch and upper inner punch, effectively dispersing lateral pressure during pressing and significantly improving mold service life.

Fastener Powder Metallurgy Die Material Selection

Fastener molds need to withstand high pressure, multiple cyclic impacts, and wear, so high-speed steel, powder high-speed steel, or tungsten carbide are generally used as mold materials, combined with vacuum heat treatment, deep cryogenic tempering, nitriding, or coating technology to improve wear-resistant lifespan. Common coatings such as TiCN, CrN, or DLC can significantly reduce friction coefficients and improve demolding smoothness.

Powder metallurgy dies are indispensable equipment for large-scale fastener manufacturing. Selecting mold suppliers with technical experience and processing capabilities can help enterprises achieve low-cost, high-consistency, and high-efficiency goals. Our company is willing to become a long-term partner in the fastener industry with customized processing services.
