TSLA.757WO/P2566-1NWO PATENT IN-MOLD FEATURE FORMING CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 63/456,351, filed March 31, 2023, the entire disclosure of which is hereby incorporated by reference in its entirety. TECHNICAL FIELD [0002] This application relates to back injecting, and more particularly relates to a method of producing intricate detail in a part using back injection pressure. BACKGROUND [0003] In the context of manufacturing metal components at mass scale, there is a need for processes capable of producing highly detailed and durable parts. Traditional metal stamping is capable of producing high detail, but not great durability. Thus, there is a need for an alternative method. SUMMARY [0004] An aspect is directed towards an in-mold logo forming on a metal sheet using back-injected plastic pressure. This manufacturing process forms a detailed embossed logo on a metal sheet faced component using the pressure of back-injected plastic. A metal sheet is cut to its starting shape and may be stamped to create an overall geometry. The metal plate may have removable tabs on its sides to assist in locating and holding the part during manufacturing. An adhesive may be applied to the backside of the metal sheet and may facilitate the aluminum bonding to the thermoplastic. The metal sheet may then be placed into a plastic injection molding tool. The cavity of the tool may have a first tool feature such as a logo that is to be embossed or engraved. The mold closes, and plastic is back injected onto the metal sheet. The pressure of the plastic forces the metal sheet to deform into the negative area or around the positive area where the first tool feature is located, forming the first feature on the part. After cooling, the part is removed from the tool and secondary operations are completed. [0005] The part now has uniform back-injected structural support under both the logo feature and the flat areas of the part, giving it superior durability over conventional stamped metal sheets attached to plastic substrates. The durability provided by the back injection allows very thin sheet metal to be used, between 0.2-1.0mm thickness. This thin sheet metal otherwise would not be able to retain its shape under load. Using thin metal further enables manufacturing of parts with intricate designs, because thin material can bend tighter radii. [0006] An aspect is directed to a sill plate for a vehicle. The sill plate comprises a metal sheet comprising a first feature, an adhesive, and a back injected layer. The adhesive layer strengthens the bond between the metal sheet and the back injected layer, and the back injected layer supports the first feature in the metal sheet. [0007] An aspect is directed to a method of forming a part. The method comprises forming a metal sheet into a first shape, placing the metal sheet into a tool, applying an adhesive to a side of the tool, and injecting a material into the tool with pressure so as to form a feature in the metal sheet.

[0040] Figure 1 is a representation of a sill plate 100 for a vehicle and a tool 200. The tool 200 is used to form the sill plate 100. In certain embodiments, the sill plate 100 may comprises an outer layer 102, an adhesive layer 104, and a back injected layer 106. The outer layer 102 may be referred to as a metal sheet or an aluminum sheet however it may be made of any metal (e.g., aluminum, stainless steel, steel, etc.) or an alternative material. In the present embodiment, the aluminum sheet has a high tensile strength, is highly formable, and anodizes well. For example, a 5000 series of aluminum exhibit these properties. More specifically, the AL 5052 series can be used in certain embodiments. In certain embodiments, the outer layer 102 may have a thickness between 0.2 mm-1.0 mm. Of course the thickness is not limited to the recited range and can have other thicknesses. [0041] The outer layer 102 comprises a first side 110 (e.g., a top surface) and a second side 112 (e.g., a bottom surface). The adhesive layer 104 may be applied to the second side 112 of the outer layer 102 and may bond the outer layer 102 to the back injected layer 106. The back injected layer 106 may be an injection material 108 such as plastic or an alternative material capable of being injected. The injection material 108 may be a thermoplastic. The thermoplastic may ideally have a low shrinkage and high dimensional stability. The injection material 108 may be a plastic such as PC, ABS, and PCABS. There may be additional materials mixed with the plastic such as Glass Fiber reinforcement which may further improve strength, stiffness, and dimensional stability. In certain embodiments, the injection material may be a PC+ABS thermoplastic with 30% glass-fiber fill. [0042] The tool 200 may comprise a first portion 210 and a second portion 230. The first portion 210 may comprise a cavity 212 and an insert 214. The second portion 230 may comprise a mold core 236 and a gate 238. The first portion 210 and the second portion 230 may form a part cavity 250. The gate 238 may be configured to facilitate the injection of the injection material 108 into the part cavity 250. In the present embodiment, the second portion 230 comprises the gate 238 but it in alternative embodiments the first portion 210 may comprise the gate 238. [0043] The insert 214 may comprise a first tool feature 216. The first tool feature 216 may comprise an embossed or engraved element in the insert 214. The first tool feature 216 is located on a tool feature face 218 of the insert 214 that contacts the outer layer 102. The first tool feature 216 may be a variety of shapes or designs such as a logo or text. The first tool feature 216 may be engraved in the tool feature face 218. [0044] Figure 2A is a representation of a tool 200. The tool 200 comprises cavity 212 and an insert 214. The insert 214 may comprise a first tool feature 216. The tool 200 further comprises holding pin 270 configured to against the outer layer 102 to hold the outer layer 102 in place when the material is injected to form the back injected layer 106. The tool 200 further comprises locating pins 260 configured to locate the outer layer 102 in a location. [0045] Figure 2B is a representation of an outer layer 102 and a tool 200. The outer layer 102 comprises the tabs 130. The outer layer is located in the tool 200. The tabs 130 interact with the locating pins 260 to locate the outer layer 102 in the tool. The locating pins 260 may interact with a locating hole 132 in the locating tab 130 to locate the outer layer 102 in the tool. The holding pins 270 may press against the outer layer 102 to hold the outer layer in place. The holding pins 270 may apply a force against the outer layer 102 during injection of the tool 200. [0046] Figure 2C is a representation of a sill plate 100 for a vehicle and a tool 200. The sill plate 100 comprises a back injected layer 106. The back injected layer 106 may comprise locating features 120, structural support 122, and engagement features 124. The locating features 120 may be used to locate the sill plate 100 when it is mounted in the vehicle. The structural support 122 may reinforce the sill plate 100 and provide structural support when in use, for example when the sill plate 100 is stepped on when someone is entering the vehicle. The engagement features 124 may serve to secure the sill plate 100 in its installed position. [0047] The sill plate 100 comprises an outer layer 102. The outer layer 102 may further comprise one or more tabs 130. The tabs 130 may be the same material and same part as the outer layer 102, or they may be different. The tabs 130 may further comprise a locating hole 132. The locating hole 132 may be used to locate or guide the placement of the outer layer 102 in the tool 200. [0048] The tool 200 may further comprise one or more locating pins 260. The locating pins 260 may interact with the one or more tabs 130, specifically the locating holes 132 of the one or more tabs 130. The tool 200 may further comprise holding pins 270. The holdings pin 270 may be located in a second portion of the tool 200 and may press against the backside of the sill plate 100 to hold it in place during the injection process. The holding pins 270 may apply a force on the sill plate 100, specifically on the outer layer 102, the adhesive layer 104, or the back injected layer 106, to hold the sill plate 100 in place. [0049] Figure 3 is a detailed cross-section representation of a sill plate 100 for a vehicle and a tool 200. The holding pin 270 presses against the outer layer 102 to hold the sill plate 100 in place when the material is injected to form the back injected layer 106. The holding pins 270 may slide out of the mold core 236 to hold the outer layer 102 during injection and then retract back into the mold core 236 mid-way through injection or once injection is complete. By retracting the pins 270 mid-way through injection, the tool 200 is able to hold the outer layer 102 in place during initial injection where it might move and the tool 200 is further able fill the holes that would be left in the back injected layer 106 by the pins 270 with injection material 108 during injection. [0050] Figure 4 is a representation of a sill plate 100 for a vehicle. Figure 4 shows the sill plate 100 from a frontal view. The outer layer 102 of the sill plate 100 comprise an aluminum sheet. The sill plate 100 further includes the tabs 130. The tabs 130 include locating holes 132. [0051] Figure 5A is a representation of a sill plate 100. The sill plate 100 includes a first feature 140 (e.g., a visual feature). The first feature 140 is located on the first side 110 of the sill plate 100. The first feature 140 corresponds to the first tool feature 216. In the present embodiment the first tool feature 216 is an engraved logo. During injection the outer layer 102 is deformed to form the first feature 140 in the form of an embossed logo. The pressure of the back injection process allows for the more precise and finite details in the first feature 140. The pressure of a typical injection molding process can be between 2,000-10,000 PSI, and the holding pressure can be about 80% of the injection pressure. In certain embodiments, both injection pressure and holding pressure are higher to ensure the outer layer 102 gets fully pressed into the cavity on the tool. In certain embodiments, the injection pressure for this process may be between 10,000-20,000 PSI. [0052] Figure 5B is a detailed representation of a portion of the sill plate 100 with the first feature 140 as seen in Figure 5A. In the present embodiment the first feature 140 comprises a logo, which includes a plurality of letters. The first feature 140 includes a plurality of finite feature details 142. In the illustrated embodiment, the finite feature details 142 comprise weld marks so as to replicate the appearance of a weld. [0053] Figure 6 is a representation of the sill plate 100 after being anodized. The anodization may occur after the sill plate 100 has been back injected. The sill plate 100 may be anodized with clear, black, or any color. [0054] Figure 7 is a representation of a method of making the sill plate 100. In step 302, the outer layer 102 (e.g., aluminum sheet) is cut to a desired shape. The shape may be the final shape or may include additional material that will be removed at a later time, such as tabs. In step 304 the outer layer 102 is stamped to form an overall geometry. The stamped shape may include curved faces and sides, bends, folds, or other geometric features. The stamping may further comprise stamping the logo and the back injection process may only be used to reinforce and provide support for the stamped logo. The step 304 may be optional depending on the overall geometry of the sill plate 100. [0055] In step 305 an adhesive is applied to a surface of the outer layer 102. The adhesive may be placed on the aluminum sheet, for example in the form of a tape. The adhesive may also be applied as a spray. The adhesive may be designed to bond polar plastic materials (PCABS, PC, ABS, etc.) to metals. The adhesive may be a multilayer film adhesive made with thermoplastic polyurethane (TPU) and modified polyolefin base. [0056] In step 306 the outer layer 102 is placed in the tool 200. The outer layer 102 may be placed in the first portion of the tool or the second. It should be understood that in certain embodiments step 305 may occur after step 306, or before step 302 or 304. The step 306 may further comprises holding the outer layer 102 in place via a plurality of tabs. The tool 200 is closed at step 308. [0057] In the step 310 the injection material 108 is injected into the part cavity 250. The plastic material is injected into the part cavity 250 through the gate 238. As the material is injected into the part cavity 250, the material fills the part cavity 250 and pushes against the second side 112 of the outer layer 102. The material may be in direct contact with the aluminum sheet or may be in contact with the adhesive layer 104. The injection material 108 applies a force on the second side of the outer layer 102, pushing the aluminum sheet into the first tool feature 216 located on a tool feature face 218 of the insert 214. The force deforms the outer layer 102 into the negative space of the first tool feature 216, forming a detailed feature in the outer layer 102 and giving the feature uniform structural support. [0058] In step 312 the sill plate 100 is removed from the tool 200. The step 312 may comprise separating the first portion of the tool 200 from the second portion of the tool 200. The step 312 can further comprise cooling the sill plate 100 before removing it from the tool 200. [0059] In step 314 secondary operations (e.g., post-processing) are completed on the sill plate 100. Secondary operations may comprise one or more of cleaning, sandblasting, anodization, removal of tabs, and other operations. The part may be sandblasted and cleaned. Then the part may be anodized with an in-organic pigment to provide durability and UV- resistance. The tabs may be used to hold the part during anodization and sandblasting. Then the tabs may be removed from the aluminum plate using a mill. The part may then be considered complete. [0060] The process and methods described in the application may further be used to create a composite structural sheet or part with aluminum on both sides. This method may also be used to create a back injected aluminum part with durable, detailed back injected features on both sides. Aluminum with pre-applied adhesive would be placed on both sides of the injection molding tool. The system may further include vacuum tubes in the tool to keep the aluminum sheets in place. The plastic may then be injected between the aluminum sheets from side gates or through holes in the aluminum sheets. [0061] It should be understood that the components described in this disclosure may be used outside of vehicles and on materials other than metal. The components described may be applicable in the aerospace, robotic, manufacturing equipment, industrial equipment, or other areas.
