Insert injection molding is a process that pre-positions metal inserts precisely within a mold, then uses injection molding to fuse the plastic and inserts together. This significantly improves product connection strength, conductivity, torsional stability, and structural reliability, and is widely used in the electrical appliances, lighting, electronics, home appliances, and toy industries. Kinghe possesses mature insert positioning mold design and automated/manual insert placement solutions, ensuring precise, accurate, and secure insert placement on every product, providing customers with high-strength, high-reliability integrated structural products.
Our professional team designs dedicated positioning molds based on customer product parameters, using high-quality steel and incorporating a precise positioning structure to avoid insert displacement and excess adhesive, ensuring product consistency and high yield.
We clean, rust-proof, and roughen the surface of metal inserts to improve bonding strength; we offer both automated (highly efficient and precise, suitable for large batches) and manual (flexibly suitable for small batches and complex inserts) placement methods to ensure precise positioning.
Utilizing advanced automated equipment, we optimize injection parameters by matching the characteristics of the insert and plastic materials to achieve integrated molding, ensuring the plastic tightly wraps the insert and avoiding loose bonding and air bubbles.
Each batch of finished products undergoes specialized strength, tensile, and torsional tests, simultaneously checking dimensional accuracy and appearance quality to ensure product reliability and lifespan.
The one-piece molding process provides a bond strength far exceeding traditional methods, preventing inserts from loosening or falling off, and improving the overall strength and lifespan of the product.
Outstanding torsional, tensile, and load-bearing performance, suitable for high-strength connection requirements in multiple fields such as electronics, home appliances, and automobiles, and adaptable to complex usage environments.
Insert Injection Molding eliminates subsequent assembly processes, reducing labor input and defect rates, lowering overall production costs, and improving production efficiency.
Positioning accuracy error ≤ ±0.05mm, avoiding insert misalignment and excess adhesive, resulting in a clean product appearance, precise dimensions, high batch consistency, and compliance with high standards.
Insert Injection Molding is widely used in LED lamp bases, terminal blocks, appliance brackets, electronic housings, toy gearboxes, motor accessories, automotive parts, power supply equipment, smart home structural components, etc.
1. Client: Domestic LED lighting company
2. Client Needs: Products require embedded nuts. Traditional processes are prone to loosening, stripping, and detachment, resulting in a 4.2% defect rate in after-sales service.
3. Service Result: Kinghe designed a dedicated precision positioning insert mold to integrally injection mold the nut, optimizing the bonding strength and stability.
Q: Will the Insert Injection Molding warp or shift during the injection molding process?
A: No, the mold uses a precision positioning structure, ensuring 100% stability and reliability.
Q: Can it be used to encapsulate copper, iron, stainless steel, or magnets?
A: Yes, we support injection molding of various metals and hardware inserts.
Q: Will the finished product pass tensile and torsion tests?
A: Yes, we have specifically optimized the structure for strength to ensure compliance.
Kinghe focuses on high-strength insert injection molding, providing stable, reliable, and high-strength structural solutions for customers in the electrical, lighting, and electronics industries, aiming to become the most trusted manufacturing partner in the industrial and component sectors.
