Global manufacturing industries including automotive, consumer electronics and daily chemical packaging are constantly pursuing high-precision, long-life and cost-effective plastic injection molds. As a professional plastic injection mold manufacturer based in China, Youkingmould has officially released a brand-new mold case showcase page at https://www.youkingmould.com/cases/. This page gathers hundreds of real delivered mold projects that have passed long-term mass production tests, covering automotive injection mold, electronic precision mold, 2K two color injection mold and automatic thread demoulding mold four core product lines. All displayed mold cases carry complete technical data, including raw plastic material matching, cavity mold steel grade, hardness parameter and international standard mold base configuration, which brings clear and reliable reference for overseas mold buyers from North America, Europe, Southeast Asia and Oceania.
All molds produced by Youkingmould fully comply with three world mainstream mold standard systems: DME for American market, HASCO for European clients and MISUMI for global general use. We adopt classified mold steel matching scheme according to different plastic materials and annual output demand, including H13, 1.2343ESR, 1.2738H and 1.2738HH hot work mold steel, with hardness controlled between HRC33 to HRC52. Our factory integrates independent DFM analysis, mold design, CNC rough and finish machining, mirror EDM, wire cutting, mold trial and after-sales modification service, forming a full one-stop custom mold solution. This article will systematically introduce our core mold cases displayed on the official case page and elaborate our manufacturing advantages in the field of precision injection mold.
Automotive plastic parts are divided into exterior appearance parts, interior structural parts, power system functional parts, filter accessories and new energy vehicle special components. Most of these products are made of glass fiber or mineral filled modified plastics, which have strong abrasion to mold cavities and strict requirements on dimensional stability, high temperature resistance and surface smoothness. The automotive injection mold series takes up the largest proportion of all projects on our case page, every single mold has stable delivery records to auto parts suppliers around the world.
Vehicle exterior and lamp parts put forward extremely high standards on surface finish, any sink mark, weld line or scratch will lead to product rejection. Our design team optimizes cooling channel, runner and gate system to eliminate surface defects fundamentally:
Chevrolet vehicle mask housing mold: Raw material ABS-PA, cavity steel H13 with HRC 50-52, MISUMI standard mold base, anti-warping structural design for large outer shell parts;
Auto rearview mirror bracket & headlamp mounting bracket mold: Main material PC-ABS alloy, matched with 1.2343ESR mold steel HRC50-52, support DME or HASCO standard as required;
Car front grille mold: Material PP+TF20, adopt 1.2738H medium hardness steel to control overall mold cost, suitable for medium-volume mass production;
Lamp socket plastic mold: Compact multi-cavity layout, stable dimensional tolerance within ±0.02mm, widely matched with vehicle lighting assembly line.
Intake manifold, high voltage connector and support frame are key load-bearing parts of automobile power system, mostly produced with high glass fiber reinforced plastic such as PA66-GF30, PA6-GF30 and PBT-GF30. These materials cause severe abrasion on mold surface, so we uniformly select wear-resistant 1.2343ESR ESR remelting steel for all power system molds:
Automotive intake manifold mold: Classic heavy-duty auto mold, long cycle continuous injection without frequent polishing, both DME and HASCO standard versions available;
New energy vehicle high voltage connector mold: Multi-core precise insert structure, anti-corrosion surface treatment for cavity, perfect for new energy car circuit connection;
Seat hinge & interior support frame mold: PA66 material, optimized ejection system to avoid deformation of thin-wall structural parts during demoulding.
With the booming development of new energy automobiles, we specially develop dedicated injection mold for PHEV and BEV vehicle plastic parts, which are fully displayed on our case page for customers’ reference:
Auto filter cover & filter housing mold: PP-TD20 mineral filled plastic, 1.2343ESR high hardness steel, HASCO standard mold base for European filter manufacturers;
Automotive battery protection box mold: PP545 raw material, thick wall uniform cooling design to guarantee assembly consistency;
PHEV battery top cover mold: Customized for plug-in hybrid vehicles, PBT-GF30 high temperature resistant material, DME international standard.
Except for automotive injection mold, Youkingmould also undertakes customized precision plastic mold for consumer electronics, smart home appliances and communication equipment. Electronic plastic components are characterized by tiny size, complex internal buckles, ultra-thin wall and mirror surface requirements. We equip high-precision 5-axis CNC and mirror EDM equipment to process mold cavity, ensuring Ra0.01 mirror effect without polishing after molding. All finished electronic mold projects are uploaded to our mold case gallery, including electronic shell, functional button, internal structural bracket and charging connector plastic parts. Whether you need small multi-cavity mold or large single-cavity electronic housing mold, you can find similar reference cases on our website and get fast DFM feedback before formal mold opening.
The 2K two color injection mold is our star customized product, widely applied in auto soft-hard composite handles, electronic anti-slip buttons, daily household tools and cosmetic packaging. Different from single color mold, our rotary type 2K mold can realize one-step integrated molding of hard plastic and soft TPE/TPR material, removing secondary bonding or assembly process, greatly reducing production labor cost and improving product sealing performance. All 2K mold cases on the website adopt balanced rotary plate structure, stable rotation without deviation during long-term continuous production, and we can adjust mold layout according to customers’ two-color injection machine parameters to achieve perfect matching.
Plastic parts with internal and external threads are very common in auto pipeline joints, cosmetic bottle caps, water pipe connectors and medical plastic fittings. Traditional manual thread demoulding method has low production efficiency and unstable thread precision, which cannot meet large-volume order demand. Our self-developed automatic thread demoulding mold uses mechanical gear and rack linkage structure, which completes thread rotation demoulding synchronously during mold opening action without extra manual operation. Each plastic product maintains consistent thread size and smooth thread surface, greatly improving production output and product qualification rate. Many mature automatic thread demoulding mold cases are displayed on our case page for buyers engaged in packaging and pipeline accessories industries.
We attach great importance to the customers' demands for product quality and rapid production.
We always believe that meeting the customers' needs is the realization of our value!
