  • Publication number: 20110060439
    Abstract: A customer sends a CAD file for the part to be manufactured to the system. The system assesses the CAD file to determine various pieces of manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be machined in two opposing orientations in a 3 axis CNC machine. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities or parts per workpiece block, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts, which may include both molded parts and total profiled machined parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer.

  • Patent number: 7630783
    Abstract: A computer program analyzes a CAD file provided by a customer of a custom part to be injection molded. Feedback from the analysis is provided to the customer through a rendering of the part. Rather than merely communicating using color as applied to the rendering file and separate text, the invention applies one or more symbols as “decals” to the rendering of the part provided to the customer. In one preferred embodiment, the symbols are chevrons or arrows which indicate the direction of additional draft needed on particular faces for the part to be sufficiently manufacturable. The symbols are sized appropriately for the size of the face to which they are applied, and are oriented to match the orientation of the face. The symbols may also indicate other information, such as the magnitude of draft needed, magnitude of thickness required, the surface finish to be applied at that location, or time or location based properties of the injection molding process.

  • Publication number: 20090125418
    Abstract: A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer.

  • Patent number: 7123986
    Abstract: A customer sends CAD files for two or more parts to be molded in a family to the system. The system provides the customer with a quotation form that allows the customer to select several family-level parameters which are independent of the shape of the part, such as material and delivery date. The quotation also allows the customer to select several part-level parameters which are independent off the shape of the part, such as quantity of each part and surface finish. The system assesses the CAD files to determine savings which can be achieved by molding the parts as a family, with multiple parts in the same mold block. If possible, the system machines cavities for the multiple parts into a single mold block, passing on reductions in cost to the customer both in the quote and in the final product delivery.

  • Patent number: 7089082
    Abstract: A first customer provides a CAD file defining the surface profile for a part to be molded to the system, and a second customer does the same for a second part. The system determines whether the materials match and the run dates overlap, thereby qualifying the parts for use in a multi-customer mold block. The system assesses the part surface profile (which could have any of a virtually infinite number of shapes) of the parts submitted and lays out the parts from multiple customers on one or more multi-customer mold blocks. Savings are generated, such as by reducing redundancies in press clean-up, in set-up, in tooling, and in surface finishing. Due to these savings, the system provides a quotation of the part to at least one of the customers which differs from the quotation that would be provided if each part was run independent of parts of other customers.

  • Publication number: 20060125249
    Abstract: A spindle for a door assembly includes a first member and a second member. The first and second members each have a base, a first leg and a second leg extending from the base. The second leg is recessed relative to the first leg. The first member confronts the second member such that the first leg of the first member confronts the second leg of the second member and the second leg of the first member confronts the first leg of the second member forming the spindle.

  • Publication number: 20050166647
    Abstract: A multi-point door lock assembly has a central lock and an extension bolt for securing the door to a door frame. The assembly has an actuator positioned at the central lock and moveable between a first and second position along an axis. The assembly further has an elongated extension bolt residing along a bolt axis. The actuator and the bolt are secured in a configuration that displaces the axis of the bolt in spaced relationship from the axis of the actuator by an adaptor having a body length. The adaptor has a first end connected to the actuator and a second end connected to the extension bolt, and an intermediate portion between the first and second ends configured to displace the bolt axis for the bolt to pass through an interior portion of an associated door member.

  • Publication number: 20050144848
    Abstract: A locking system for a movable member supported by a support frame, the support frame having an engagement surface, the locking system comprising a lock member and an input device adapted to be mounted on the movable member the input device being operably connected to the lock member. The input device is rotatable to move the lock member from a first position to a second position, the second position defining a locked position wherein the lock member is adapted to be in contact with the engagement surface. The locking system also includes a link arm and a spring that permits additional rotation of the input device after the lock member reaches the locked position, if necessary.

  • Publication number: 20040199838
    Abstract: An integrated circuit or other electronic circuitry is tested by arranging device pins into multiple-pin groups, and permitting the device pins of the group to share a single tester channel of a piece of test equipment. More particularly, a group comprising a plurality of device pins of the electronic circuitry is designated, and assigned to one of a plurality of tester channels in the test equipment. A test may then be performed on the electronic circuitry, via the assigned tester channel, utilizing at least a subset of the device pins in the designated multiple-pin group. Advantageously, the invention allows high pin count integrated circuits to be tested using inexpensive test equipment platforms.

  • Patent number: 5924435
    Abstract: A method of energizing an electromagnetically operable valve which comprises a valve member movable into engagement with a seating when a winding is energized comprising connecting the winding to a DC supply to achieve a rapid rate of rise of current. The current is controlled at the peak value and is then reduced to a low value after an initial movement of the valve member. The valve member continues its movement towards the seating and the current is restored prior to engagement of the valve member with the seating to substantially eliminate bouncing of the valve member away from the seating.
