Under-the-Hood Molds

Under-the-Hood Molds are mass-produced core plastic parts for the entire automotive engine compartment, covering five core categories: intake system components, cooling system components, engine hood and protective components, electrical and sensor components, and sealing and protective components.

Leveraging the advantages of lightweight, high precision, one-piece molding, and multi-functional plastic parts, the molds are fully compatible with vehicle manufacturing standards, meeting industry requirements for vehicle power performance, driving safety compliance, and automotive emissions environmental protection.

Notably, KRMOLD can customize Under-the-Hood Molds on demand, covering Plastic Battery Case Injection Molds, Plastic Auto Parts Sensor Injection Molds, Plastic Car Radiator Tank Molds, Gearbox Housing Injection Molds, Auto Engine Cover Injection Molds, Automotive Fan Radiator Molds, and Plastic Turbocharger Housing Molds, adapting to the mass production needs of all vehicle types, including gasoline vehicles, hybrid vehicles, and new energy electric vehicles.

I. Complex Structure Molding Capability:

Engine compartment intake manifolds, engine hoods, oil pans, and other plastic parts have complex structures with dense holes, slots, reinforcing ribs, and positioning bosses. KRMOLD optimizes the core module structure of Under-the-Hood Molds—cavities, cores, sliders, and ejector pins—and optimizes the mold opening and closing and injection molding processes.

Relying on customized Under-the-Hood Molds, complex three-dimensional plastic parts can be injection molded in one go, with dimensional accuracy strictly controlled within ±0.1mm, perfectly matching the precision assembly standards of the entire vehicle.

II. Integrated Design:

KRMOLD optimizes the integrated mold architecture of Under-the-Hood Molds, enabling integrated injection molding of multiple parts. It can integrate spliced plastic parts such as engine hoods and radiator grilles into single-unit components. Leveraging high-performance Under-the-Hood Molds reduces the number of parts, fasteners, and assembly processes, thereby decreasing the weight of plastic parts and overall vehicle production costs.

It also strengthens the overall structural integrity of engine compartment plastic parts, eliminating gaps and abnormal noises during driving.

III. Adapting to Product Innovation:

KRMOLD customized Under-the-Hood Molds flexibly adapt to designers' new engine compartment plastic part designs and functional solutions. The adjustable Under-the-Hood Molds enable rapid implementation of the entire process from new product development and prototyping to mass production, accelerating product iteration for automakers and aligning with market demands for functional and aesthetic changes in automotive engine compartments.
